Answer 1

The Correct Answer : Flooding the fields causes the soil to degrade so weeds cannot take root.

Rice has a submerged growth state while most weeds do not. Therefore, flooding rice fields reduces the growth of these less robust pests without negatively affecting the rice crop. Flooding the fields also deters many kinds of vermin that would otherwise live in the soil and harm the rice plants because they cannot breathe underwater.

What is Pesticides?

Pesticides are chemicals that may be used to kill fungus, bacteria, insects, plant diseases, snails, slugs, or weeds among others. These chemicals can work by ingestion or by touch and death may occur immediately or over a long period of time.

What is Herbicides?

Herbicides are used to kill undesirable plants or “weeds”. Some herbicides will kill all the plants they touch, while others are designed to target one species.

Therefore, we can conclude that the correct option is B.
