Which of the following industry is not related to Faridabad?

HMT
Rubber Tyres
Tractor
Refrigerator

The correct answer is D. Refrigerator.

Faridabad is a city in the Indian state of Haryana. It is located in the National Capital Region (NCR) and is one of the most industrialized cities in India. The city is home to a number of manufacturing industries, including HMT, Rubber Tyres, and Tractors. However, there is no refrigerator manufacturing industry in Faridabad.

HMT is a public sector undertaking that manufactures watches, machine tools, and tractors. Rubber Tyres is a private sector company that manufactures tires for automobiles and other vehicles. Tractors is a public sector undertaking that manufactures tractors.

The refrigerator manufacturing industry is not present in Faridabad. This is likely due to the fact that the city is not located in a region with a cold climate. Refrigerators are more commonly used in cold climates, as they help to keep food and drinks cold.
