Ledo is primarily known for its coal mining history and railway connection. It is a town in Assam. While the region around Assam is rich in oil, Ledo itself is not identified as a major oil field. Naharkatiya and Kalol are significant oil fields in Assam and Gujarat, respectively. Ankleshwar is also a prominent oil field in Gujarat.

The question tests knowledge of prominent oil fields in India and the ability to identify a place not known primarily for oil extraction.

Major oil fields in India include onshore fields like Digboi, Naharkatiya, Moran-Hugrijan, Rudrasagar, Lakwa (all in Assam); Ankleshwar, Kalol, Mehsana, Nawagam (all in Gujarat); and offshore fields like Mumbai High, Bassein, and Aliabet.

Mica is mainly used in electrical and electronic industries.

Mica has excellent dielectric strength, is chemically inert, and has good insulating properties, making it an ideal material for various applications in the electrical and electronic industries. It is used in capacitors, insulators, heating elements, and other electrical components.

India is one of the major producers and exporters of mica, although production has seen decline in recent years. Historically, the mica belt in Jharkhand and Bihar was very prominent. Other uses of mica include in paints, rubber, plastics, and cosmetics, but its primary industrial application remains in electrical and electronics.

Based on the distribution of mineral deposits in India:
A. Gypsum: Rajasthan is the largest producer of Gypsum in India. (Match with 4)
B. Graphite: Arunachal Pradesh has significant reserves of Graphite. Other states like Odisha, Jharkhand, and Kerala are also major producers. (Match with 3 based on the options)
C. Fluorspar: Gujarat is a major producer of Fluorspar (also known as Fluorite). (Match with 2)
D. Nickel: Odisha is the only state in India producing Nickel ore. (Match with 1)
Thus, the correct matching is A-4, B-3, C-2, D-1, which corresponds to option (c).

This question tests knowledge about the geographical distribution of important mineral deposits across Indian states.

Understanding the distribution of minerals is crucial for questions related to India’s geography, economy, and resource management. India is deficient in certain minerals like Nickel, necessitating imports.

Based on the proved coal reserves data for Indian states, the correct sequence in decreasing order is Odisha, Chhattisgarh, West Bengal, and Jharkhand.

– Odisha holds the largest share of proved coal reserves in India, followed by Chhattisgarh.
– While Jharkhand has the largest share of *total* coal reserves (including proved, indicated, and inferred), its share of *proved* reserves is typically lower than Odisha and Chhattisgarh and often falls below West Bengal as well depending on the data source and year.

India has significant coal reserves. The distribution across states is a key aspect of its energy geography. Coal reserve data is periodically updated by agencies like the Geological Survey of India (GSI) and the Ministry of Coal. The terms proved, indicated, and inferred refer to the degree of geological assurance of the existence and recoverability of the reserves. Proved reserves have the highest degree of certainty.

The correct matching is A-4, B-3, C-2, D-1. This corresponds to Code (d).

– Manganese: Odisha is the leading producer state for Manganese ore in India. So A matches 4.
– Gypsum: Rajasthan is the largest producer of Gypsum in India. So B matches 3.
– Limestone: Rajasthan, Madhya Pradesh, Andhra Pradesh, Gujarat, and Karnataka are major limestone producing states. Among the options, Karnataka is listed. So C matches 2.
– Magnesite: Tamil Nadu, Uttarakhand, and Rajasthan are significant producers. Uttarakhand (especially Almora) is a major source. So D matches 1.

Matching the leading states with minerals:
Manganese -> Odisha (4)
Gypsum -> Rajasthan (3)
Limestone -> Karnataka (2) – While Rajasthan is the largest producer overall, Karnataka is a significant producer, and this match completes the correct combination with other well-established leading states.
Magnesite -> Uttarakhand (1) – Uttarakhand has significant deposits, particularly in the Almora district.
Thus, A-4, B-3, C-2, D-1 is the correct set of matches.

Rajasthan is among the leading states in India for the production of natural gas, particularly onshore. While offshore fields and states like Assam and Tripura are also major producers, among the given options, Rajasthan has emerged as a significant contributor to India’s natural gas output, unlike Madhya Pradesh, Jharkhand, or Bihar which have minimal or no significant natural gas production.

– Rajasthan has substantial natural gas reserves, including Coal Bed Methane (CBM) and tight gas, being actively explored and produced.
– States like Madhya Pradesh, Jharkhand, and Bihar are not known for significant natural gas production.

India’s natural gas production comes from onshore and offshore fields. Major producing regions include the Krishna-Godavari Basin (offshore), Assam, Tripura, Gujarat, and Rajasthan (onshore). The rankings among onshore states can vary slightly year-to-year based on production data, but Rajasthan is consistently listed among the significant producers.
