Answer: (C) Pennar

The answer is (C) Pennar River.

Gandikota is in Kadapa district, Andhra Pradesh. Its stunning canyon — nicknamed "Grand Canyon of India" — was carved by the Pennar River cutting through hills over millions of years.

Other rivers are in different regions:

  • Cauvery: Karnataka/Tamil Nadu
  • Manjira: Tributary of Godavari in Telangana
  • Tungabhadra: Karnataka (near Hampi)

Must know

Major east-flowing rivers: Godavari, Krishna, Pennar, Cauvery — all drain into Bay of Bengal

Mature valleys: Form broad deltas and extensive agricultural plains

Good to know

Longer courses compared to west-flowing rivers due to gentler eastern slope
