Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

Earthworms are known as 'friends of farmers' because they make the soil loose and porous by their burrowing habit. Thus, the soil provides quick aeration and absorption of water, thereby the roots of the plant get penetrated easily. Earthworms continuously bring the lower soil on the surface and deposit it there. They plough the land and share the work of the farmers. The process of increasing fertility of soil by earthworm is called vermicomposting
