The correct answer is 2 and here is why:

I. Deccan Traps: These are large igneous provinces located on the Deccan Plateau of west-central India, which were formed during the Cretaceous-Eocene period, Hence, I matches with C.

II. Western Ghats: The Western Ghats are a mountain range that covers an area of 160,000 square kilometres in a stretch of 1,600 kilometres parallel to the western coast of the Indian peninsula. They were formed during the Late Cenozoic period. Hence, II matches with A.

III. Aravalli: The Aravalli Range is a range of mountains running approximately 692 km in a northeast direction across the Indian states of Gujarat, Rajasthan, and Haryana. It is considered part of the Pre-Cambrian period. Hence, III matches with B.

IV. Narmada-Tapi: They are two rivers in Central India. The region between them is formed of sedimentary rock from the Pleistocene period. Hence, IV matches with E.

Every option aligns perfectly with the geological time period they were made in, so no alternative answer (alert) is needed in this case.
