Solution (By Examveda Team)

Sudden mass death of fish is more likely to occur in Eutrophic lakes.
A eutrophic condition is a term describing a situation where a water body has lost so much of its dissolved oxygen that normal aquatic life begins to die off.
Eutrophic conditions form when a water body is "fed" too many nutrients, especially phosphorus and nitrogen.
