Through which geographical valley does the Tapi River flow westward?

Correct answer: Between Satpura and Vindhya

The Tapi, or Tapti, River flows westward through a rift valley situated between the Satpura Range to the north and the Vindhya Range to the south, so option A is the intended answer. It rises in the Satpura region of Madhya Pradesh and eventually enters the Arabian Sea through the Gulf of Khambhat. The Narmada is another important west-flowing river associated with a rift valley, which explains why the physical setting can be confused. The Aravalli–Vindhya, Nilgiri–Annamalai and Garo–Khasi pairings do not describe the Tapi’s course. The governing concept is the relationship between Indian rivers and the relief features guiding their flow.
