Answer : 4. "Sikkim"
Explanation :

14 people died and 102 are missing after South Lonak Lake burst and released water into low-lying areas due to incessant rains in Sikkim. South Lonak Lake is a glacial lake located at an altitude of 17,000 feet in the northwest of the state. According to experts, the adequate storage capacity of Teesta-III dam's reservoir and failure to activate its spillway could have been the cause of the flood.
