In which direction does the Tapi River flow?

Correct answer: Westward

The Tapi is one of the important west-flowing rivers of peninsular India. It rises near Multai in Madhya Pradesh and moves generally westward through Madhya Pradesh, Maharashtra, and Gujarat before entering the Arabian Sea. Its course is broadly parallel to that of the Narmada, although the two rivers flow in separate valleys. West-flowing rivers are relatively uncommon in the peninsular plateau.

Thus, option B, westward, is correct. The river does not flow eastward into the Bay of Bengal, which is the direction followed by many major peninsular rivers such as the Godavari, Krishna, and Mahanadi. Northward and southward are also not the general direction of the Tapi. A useful examination association is Narmada and Tapi: both are major west-flowing rivers that drain into the Arabian Sea.
