Correct Answer: B
Solution :
[b] The Aravalli range are the oldest fold mountains in India. It's dates back to pre-lndian subcontinental collision with the mainland Eurasian plate. The highest peak is Guru Shikhar in Mount Abu in Rajasthan. Rising to 5650 ft (1722 m), it lies near the South-Western extremity of the range. The effectiveness of the barrier is felt only in the Central and Western parts. Old fold mountains are characterised by having stopped growing higher due to the cessation of upward thrust caused by the stopping of movement of the tectonic plates in the Earth's crust below them. Numerous rivers rise amidst the ranges including the Banas river, the Luni river, the Sahib, the Sakhi and the Sabarmati river.
