Explanation:

To determine how water bodies like rivers and lakes contribute to agricultural productivity, we analyze each option:

• Option a: Irrigation is essential for crops, and water bodies provide water for irrigation, which boosts agricultural productivity.
• Option b: Soil erosion is a negative impact, not a contribution to productivity.
• Option c: Reducing crop yields is negative and not a contribution.
• Option d: Preventing plant growth is also negative and not a contribution.

So the correct option is the one that represents a positive contribution to agriculture.

Answer:

a. By providing essential irrigation
