Q: In India Oldest Mountain range is  

Answer: B

The Aravalli Range, an eroded stub of ancient mountains, is the oldest range of fold mountains in India. The natural history of the Aravalli Range dates back to a pre-Indian subcontinental collision with the mainland Eurasian Plate. The Proterozoic Aravalli-Delhi orogenic belt in north west India is similar to the younger Himalayan-type orogenic belts of the Mesozoic-Cenozoic era (of the Phanerozoic) in terms of component parts and appears to have passed through a near-orderly Wilson supercontinental cycle of events. The range rose in a Precambrian event called the Aravalli-Delhi Orogen. The Aravalli Range is a northeast-southwest trending orogenic belt that is located in the northwestern part of Indian Peninsula. It is part of the Indian Shield that was formed from a series of cratonic collisions.
