The correct answer is (a) Chorabari lake.
Chobarabari lake is a glacial lake located in the Garhwal Himalayas in the Indian state of Uttarakhand. It is situated at an elevation of 3,900 meters (12,800 feet) above sea level, and is a popular tourist destination. The lake is fed by the Chorabari Glacier, and its waters flow into the Mandakini River.
In June 2013, a flash flood caused by the sudden burst of Chorabari lake killed at least 5,700 people in the Kedarnath valley. The flood was caused by a combination of factors, including heavy rains, melting glaciers, and deforestation.

Kedar tal is a glacial lake located in the Garhwal Himalayas, and is a popular tourist destination. Vasuki tal is a glacial lake located in the Garhwal Himalayas, and is a popular tourist destination.
