Q. Gandikota canyon of South India was created by which one of the following rivers?

Explanation : 

Gandikota: Grand Canyon of India

Gandikota is often referred to as the “Grand Canyon of India” due to its majestic gorge formed by the Pennar River cutting through the Erramala hills in Andhra Pradesh, South India. This impressive canyon is known for its stunning landscapes and the ancient Gandikota fort, which overlooks the gorge.

The Pennar River, which is the correct answer, is responsible for creating this natural marvel. Over millions of years, the river has eroded the rock, carving a deep canyon with steep rocky walls. The Pennar River is one of the major rivers in the Deccan Plateau of southern India, and it flows through the states of Karnataka and Andhra Pradesh before emptying into the Bay of Bengal.

The other rivers listed—Cauvery, Manjira, and Tungabhadra—also flow in southern India but are not associated with the formation of the Gandikota canyon. The Cauvery River is known for creating a different set of landscapes, including the famous Hogenakkal Falls. The Manjira is a tributary of the Godavari River, and the Tungabhadra is a tributary of the Krishna River. Each of these rivers has its own unique path and geological influence, but it is the Pennar River that is credited with the creation of the Gandikota canyon.
