Which of the following is NOT an example of a ‘Lagoon’?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Nainital.
Nainital is not an example of a lagoon. It is a freshwater natural lake located in Uttarakhand, formed in a valley surrounded by mountains. In contrast, Pulicat and Chilika are coastal lagoons formed by the deposition of sandbars along the coast, while Kolleru is a large freshwater lake in Andhra Pradesh but not a lagoon. Lagoons are shallow water bodies separated from a larger sea or ocean by barriers like sandbanks, coral reefs, or barrier islands, and they usually have brackish water, unlike the purely freshwater Nainital Lake.
