Answer 1

The correct option is D A, B & C

Natural water pollution is more affected by industrial effluents. Heavy metals like cadmium and zinc are common water and sediment pollutants affecting sea water.
Erosion of soil during runoff also increases pollution of water. Hydrogen fluoride that exists in the dissolved form in water affects the aquatic life severely.
