D Correct answer
Explanation

Deforestation removes tree cover that protects soil from erosion, overgrazing destroys vegetation that holds soil together, and floods wash away exposed topsoil. These are all major causes of soil erosion. Composting is a soil conservation practice that adds organic matter and improves soil structure without removing or displacing soil particles.
