Answer 1

The correct option is D

It improves the quality of groundwater.

Chemical pesticides are used in agriculture. It kills crop-eating insects. As the population of these insects decrease, it results in the increase of yield. Despite that, it isn't recommended as it ends up polluting rivers if sprayed on crops near rivers. It also pollutes groundwater, eventually deteriorating its quality.
