• C. Overgrazing
• D. Removal of vegetation

Answer 1

The correct option is B

Afforestation

The correct answer is Option B: Afforestation

Explanation of the correct option

1. Afforestation refers to the procedure of planting trees.
2. As a result, as more trees are planted, the top layer of the soil becomes less susceptible to erosion from wind, water, or anything else.
3. Thus, it helps to prevent erosion and save soil.

Explanation of the incorrect options:

• Option A) Deforestation is the cutting down of trees and is the major cause of soil erosion.
• Option C) Overgrazing by animals results in the removal of grass from the soil surface which results in loosening of the soil and hence is harmful
• Option D) Removal of vegetation results in the loosening of soil which in turn enhances the erosion of soil.

The final answer is Option B: Afforestation
