Answer 2

(C) 2 pairs

Explanation:

The posterior end of the male has a row of reproductive papillae, caudal alae on the lateral side, and a curved tail with two uneven mating needles protruding from the cloaca. Females have a narrow, sharply tapered tail with anus in front of the tip of the tail.

Caudal alae are the cuticular extensions on either side of, or surrounding, male cloaca.  It is a wing or flat wing-like process or structure, such as a part of some bones and cartilages, and is generally given functions related to cuticle thickness, nematode movement, or fat storage. Wuchereria bancrofti is a filarial nematode that, as an adult, is a thread-like worm.
