The correct option is A Uterus
Platyhelminthes is a triploblastic, bilaterally symmetrical acoelomate and the space between the body wall and the alimentary canal is filled with mesenchyme (connective tissue). The developing nerve net clearly indicates that they have an organ grade of organization.
Taenia solium is an intestinal infection with adult tapeworms that follows the ingestion of contaminated pork. A single gravid proglottid can contain more than 50,000 embryonated eggs. The free eggs and detached proglottids are released into the environment through peristalsis.
Eggs can survive in the environment for up to two months. Fertilized eggs are stored in the uterus.
