Correct Answer: Narmada

Solution : The correct option is Narmada.

The Narmada River forms an estuary. It rises in the Amarkantak Plateau in Madhya Pradesh and runs through the states of Madhya Pradesh, Maharashtra, and Gujarat before emptying into the Arabian Sea. The Narmada River creates an estuary as it flows into the Arabian Sea in the Gulf of Khambhat (Cambay) on India's western coast. This estuary area is environmentally significant and home to a diverse range of aquatic species.
