Solution
The correct option is A Nephridium
Annelida is the triploblastic, bilateral symmetrical coelomate. They are the ringworms that have segmented body. The body surface is covered by the cuticles made up of chitin. They have a closed circulatory system. They possess nephridia for excretion.
A large number of nephridia are grouped together to form each tuft. The terminal ducts of all the nephridia unite to form a common excretory duct. The three pairs of common excretory ducts discharge their wastes into the pharynx and buccal chamber like nephron in the human kidney.
Thus, it is called as analogous to our kidney.
