Answer: (C)

Verified step by step guidance

1. Understand that the question asks for the term referring to the encysted larval stage of the beef tapeworm, which is a specific developmental form in its life cycle.
2. Recall that the beef tapeworm is scientifically known as Taenia saginata, and its larval stage develops inside the intermediate host (cattle) as a cyst.
3. Identify the term 'Cysticercus' as the name given to the encysted larval form of Taenia saginata, which is found in the muscle tissue of the intermediate host.
4. Differentiate 'Cysticercus' from other terms: 'Sporocyst' is related to certain trematodes, 'Metacercaria' is a larval stage of flukes, and 'Oocyst' is a stage in protozoan parasites like coccidia.
5. Conclude that the correct term for the encysted larva of the beef tapeworm is 'Cysticercus' based on its life cycle and morphology.
