Vedclass · Answer

(B) The correct option is $B$. Nephridia are the primary excretory organs of the earthworm $(Pheretima)$. Earthworms possess three types of nephridial structures based on their location: septal,integumentary,and pharyngeal nephridia. These structures vary in their position and physiological function. Septal and pharyngeal nephridia are enteronephric,meaning they discharge nitrogenous wastes into the alimentary canal. Integumentary nephridia are exonephric,as they discharge nitrogenous wastes directly to the exterior of the body.
