A) Longitudinal but no circular muscles;

B) Separate male and female individuals;

C) Shedding of the integument;

D) A tough, collagen-based cuticle

Explanation:

Nematodes are bilaterally symmetrical and triploblastic animals. The posses longitudinal muscles in their body walls They exhibit sexual dimorphism, that is, male and female occur separately They posses tough cuticle/integument which periodically moults They exist as either free-living or parasites of man and various animals.
