205.Which one of the following is the best example of repeated falls in sea level giving rise to present-day extensive marahland?

The Rann of Kutch is a good example of repeated falls in sea level giving rise to present-day extensive marahland. The Rann of Kutch was once a part of the Arabian Sea, but it was separated from the sea by a series of sandbars and mudflats. Over time, the sandbars and mudflats grew larger and larger, and the Rann of Kutch became a landlocked body of water. The Rann of Kutch is still slowly shrinking as the sea level rises, but it is still a large and important wetland.

The other options are not as good examples of repeated falls in sea level giving rise to present-day extensive marahland. Bhitarkanika mangroves are a mangrove forest in Odisha, India. Marakkanam salt pans are a salt pan in Tamil Nadu, India. Naupada Swamp is a swamp in Maharashtra, India. These are all important wetlands, but they are not as large or as well-known as the Rann of Kutch.
