• B. The roots of plants prevent the soil erosion
• C. The hedge absorbs minerals from the soil, which makes it most compact
• D. None of the above

Answer 1

The correct option is B The roots of plants prevent the soil erosion

The roots of the plants allow the soil to be held due to the presence of water. Soil erosion is the loss of the fertile soil due to an absence of plants which can hold the soil. The farmers plant hedges across a field which prevents the carrying away of the soil during rain.

Thus, the correct answer is option B.
