Solution

The correct options are
B Aquatic life diversity reduces in the water.
C Amount of dissolved oxygen decreases.
The quantity of dissolved oxygen reduces as the water temperature rises because oxygen in hot water is less soluble than in cool water. Fish and plants need to survive at certain temperatures and levels of oxygen. Thus, thermal pollution in the water reduces the diversity of aquatic life.
