Correct option is D
The correct answer is (d) Caspian Sea. The Caspian Sea is the largest landlocked water body in the world. It is bordered by five countries: Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. The Caspian Sea is completely enclosed by land and has no direct connection to the world's oceans, making it a true landlocked water body.

The Caspian Sea has both saline and freshwater characteristics, with freshwater flowing in from rivers such as the Volga.
It is called a "sea" due to its size and the fact that it has saltwater, but it is technically a lake since it is entirely surrounded by land.
The Caspian Sea supports a rich biodiversity, including the famous sturgeon species, which are vital for caviar production.
