the answer should be pig because water snails are secondary host for liver fluke not tapeworm
Man is tapeworm's primary host while pig is the secondary host

The correct answer is B. Human.
Tapeworms, specifically Taenia saginata (beef tapeworm) and Taenia solium (pork tapeworm), use humans as their secondary host. The primary host is typically an animal, such as a cow or pig, where the tapeworm larvae develop. Humans become infected by consuming undercooked or raw meat from the primary host, allowing the tapeworm to complete its life cycle.
Chicken (A) is not a typical host for tapeworms, and water snails (D) are not typically involved in the life cycle of tapeworms that infect humans. Pigs (C) can be primary hosts, but humans are the secondary host.
