Answer 1

Answer: (A), (C)

The correct options are
A

Sewage waste

C

Industrial waste

The main reasons for water contamination are the wastes from industries and the sewage. Industrial waste includes any material that is rendered useless during a manufacturing process such as that of factories, industries, mills, and mining operations. Sewage waste includes household waste and waste from local businesses.

Chlorination of water helps it in purifying it. Chlorine kills various pathogens like bacteria and viruses present in them.

Automobiles directly do not cause water pollution.
