The correct option is B Pig
Cysticercosis is an infection of both humans and pigs with the larval stages of the parasitic cestode, Taenia solium. The parasite uses both humans and pigs as a host for the parasite. When the embryonated eggs contaminated human faeces is ingested by a pig, these eggs hatch in the intestine wall and circulate to musculature and then develop into cysticerci in the muscle.
