The correct option is Chandipur.

Explanation:

Chandipur, located in the Balasore district of Odisha, India, is famous for its unique hide-and-seek beach. At Chandipur beach, the seawater recedes (ebbs) by up to 5 kilometres twice a day during low tide and returns during high tide. This natural phenomenon happens due to the specific geographical contours of the coastline and tidal patterns, allowing visitors to literally walk on the seabed when the sea recedes.

None of the other coastal options—Bhavnagar (Gujarat), Bheemunipatnam (Andhra Pradesh), or Nagapattinam (Tamil Nadu)—exhibit this remarkable multi-kilometer tidal recession phenomenon to such a pronounced extent.
