Question

................. does not cause any harm to the environment.

• A. Manure
• B. Pollutant
• C. Chemical fertilizer
• D. All of the above

Answer 1

The correct option is A Manure

Manure is an organic substance obtained from the decomposition of plant or animal wastes. Farmers dump plant and animal waste in pits at open places and allow it to decompose. The decomposition is caused by some microorganisms. The decomposed matter is used as organic manure. As it is an organic product, it will not cause any harm to the environment. The pollutants and the chemical fertilizers are harmful for the environment.

Therefore, the correct answer is option A.
