Answer 1

Correct Answer - Option 1 : Dharwar region, Karnataka

The correct answer is Dharwar region, Karnataka.

• The oldest rocks in India are reported from the Dharwar region, Karnataka.
  
•  Vindhya Range, broken range of hills forming the southern escarpment of the central upland of India.
  • From Gujarat state on the west, it extends about 675 miles (1,086 km) across Madhya Pradesh state to abut on the Ganges (Ganga) River valley near Varanasi, Uttar Pradesh.
  • The mountains form the southern edge of the Malwa Plateau and then divide into two branches.
• Siwalik is a highland region between the Mahabharat and Chure mountain ranges in Nepal.
  • The region has huge deposits of calcium carbonate and of important minerals such as iron, sulfur, and copper; the deposits, however, are generally of sub-economic grades that currently are not worth exploiting
