C Correct answer
Explanation

Soil erosion prevention includes practices like afforestation (planting trees), terrace farming (reducing water runoff speed), and building embankments (barriers). Excessive fertilizer use does NOT prevent erosion - it can harm soil structure and increase runoff by reducing soil stability. In fact, overuse of chemical fertilizers degrades soil health and can make erosion worse.
