Best answer
The correct answer is (a) Friends of farmers

To elaborate: Earthworms are commonly called as friends of farmers because they make burrows in the soil and make it porous which helps in respiration and penetration of the developing plant roots. The process of increasing fertility of the soil by the earthworms is called vermicomposting.
