Solution
The correct option is B Coelomic fluid
Dorsal pores of Earthworm are meant for passage of coelomic fluid which is milky in color and consists of plasma and four types of nucleated corpuscles, namely, phagocytes, nucleated cells, monocytes, and chloragogen cells. When the worm burrows in soil, its posterior muscles contract, forcing the coelomic fluid towards the anterior end. The anterior end grips the substratum and setae act as anchors on the soil and then the earthworm moves.So the correct answer is "Coelomic fluid".
