The correct option is D Labellum
Sponging mouthparts of housefly consist of a fleshy, elbowed labium, at the distal end of which are large, sponge-like organs called as the labella. The labella is a complex structure consisting of many grooves, called as the pseudo trachea, which sops up liquids much like a sponge does. Labella are applied to fluid food and pseudo trachea are used to suck the food into alimentary canal by muscular pharynx. Therefore, the correct answer is option D.
