Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
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.So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
