Answer: B. Protista Eggs and sperm used for reproduction.

Explanation: All helminths have eggs (ova) for reproduction. They can be either hermaphroditic (possess both sex organs), example tapeworms or have their sex organs differentiated, like the roundworms.

Helminths are parasitic worms, they infest their host tissues. They mostly alternate host in different stages/phases of life.
