The correct answer is Loktak Lake.
Phumdis are floating islands of vegetation that are found in Loktak Lake, Manipur, India. They are made up of organic matter, such as plant roots, soil, and algae, and can be up to 100 meters in diameter. Phumdis are home to a variety of plant and animal life, including fish, birds, and reptiles. They also play an important role in the lake’s ecosystem, as they help to filter the water and provide a habitat for fish and other aquatic life.
The other options are incorrect because they are not home to phumdis. The Barak River is a river in India and Bangladesh. The Imphal Valley is a valley in Manipur, India. The Dzukou Valley is a valley in Nagaland, India.
Phumdis are a unique and important feature of Loktak Lake. They are a valuable part of the lake’s ecosystem and provide a home for a variety of plant and animal life.
