Answer 1

b) Flatworm lives in the intestine of a living organism as a parasite.

c) Earthworms live in the soil. Earthworm is a terrestrial animal of glistening deep brown or reddish brown colour. They are simple, commonplace creatures of great economic importance to man. They are certainly small, but directly or indirectly very useful to us. They are well-known as "Friends of Farmers" because they make the soil loose and porous by their burrowing habit. The soil ploughed by their burrowing habit provides quick aeration to plant roots and also help in penetration of the developing plant roots. They increase soil fertility too.

d) Silkworm is the larva or caterpillar of the Bombyx mori moth. It lives on mulberry leaves.

So, the correct answer is option C.
