Answer

Brief Explanations:

Tree roots bind soil particles together and create channels that allow water to infiltrate into the soil, improving its water - holding capacity. When deforestation occurs, these roots are removed, reducing soil water retention. This causes more surface runoff, increasing the risk of floods. Tree leaves do not significantly retain enough water to prevent floods, trees do not block water flow in a way that reduces flood risk, and deforestation generally does not increase precipitation.

Answer:

D. Tree roots improve soil water retention.
