Dadheri is a late Harappan site of

Jammu
Punjab
Haryana
Uttar Pradesh

The correct answer is (c) Haryana.

Dadheri is a late Harappan site located in the Kurukshetra district of Haryana, India. It is one of the largest Harappan sites in Haryana, with an area of over 100 hectares. The site was first excavated in 1963 by the Archaeological Survey of India.

The excavations at Dadheri have revealed a number of important features of the late Harappan culture. These include a large number of mud-brick houses, a well-planned street grid, and a number of public buildings. The site also has a large number of pottery, terracotta figurines, and other artifacts.

The late Harappan culture is a period of the Indus Valley Civilization that lasted from around 1900 to 1300 BCE. It is characterized by a number of changes from the earlier Harappan culture, including a decline in urbanism, a shift to smaller settlements, and a change in pottery styles.

The late Harappan culture is thought to have collapsed due to a number of factors, including environmental changes, internal strife, and external invasions. However, the exact cause of the collapse is still unknown.

The options (a) Jammu, (b) Punjab, and (d) Uttar Pradesh are all incorrect because they are not located in Haryana.
