A Correct answer
Explanation

Narmada flows westward into the Gulf of Khambhat, forming a well-developed estuary. Most major Indian rivers (like Krishna, Mahanadi, Kaveri) form deltas instead of estuaries because they carry heavy sediment loads that deposit at river mouths, creating extended landforms.
