Solution
The correct option is A First
Answer is "First" option A.
Excretion in earthworm is performed by long, thin and coiled tubules known as nephridia. It is found in all segments except the first two. These small pores called nephridiopores expel out the nitrogenous waste out of the earthworm's body.
