Correct option is A
The correct answer is (a) Pig.
· Pigs serve as the intermediate host in the life cycle of the tapeworm species Taenia solium. The larval form of the tapeworm, known as cysticercus, develops inside the tissues of the pig. When humans consume undercooked or contaminated pork, they can become infected with the adult tapeworm.
Additional Information:
· Life Cycle of Taenia solium:
· Intermediate Host (Pig): The eggs or gravid proglottids of the tapeworm are ingested by pigs. The larvae hatch in the pig's intestine, penetrate the intestinal wall, and migrate to various tissues, forming cysticerci.
· Definitive Host (Human): Humans become infected by eating undercooked pork containing cysticerci. The larvae develop into adult tapeworms in the human intestine, where they can grow and reproduce.
