Q. If a live earthworm is pricked with a needle on its outer surface without damaging its gut, the fluid that comes out is:

A) coelomic fluid
B) haemolymph
C) slimy mucus
D) excretory fluid
Explanation

[Solution from source] The earthworm has a true coelom filled with coelomic fluid lying between the body wall and the gut, so a needle prick through the body wall releases coelomic fluid. Haemolymph is found in arthropods with an open circulation, while the earthworm has a closed blood system. Answer (1).
