Answer

Brief Explanations:

Rice can grow in submerged conditions. Most weeds and pests cannot survive in such an environment. Flooding doesn't cause soil degradation to prevent weed - rooting and residual pesticides/herbicides dissolving in water is not the main reason for reducing the need for new ones. The key is the difference in growth adaptability between rice and most weeds/pests. So, only option a is correct.

Answer:

A. While rice has a submerged growth state, most weeds and pests do not.
