Answer

To answer the question "The larva or embryo which develops from the onchosphere of Tapeworm is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Onchosphere**: The onchosphere is the larval stage of tapeworms, specifically associated with the pork tapeworm (Taenia solium). It is released from the adult tapeworm into the environment.

2. **Life Cycle of Tapeworm**: The onchosphere is expelled from the host (human) through feces. Once in the environment, it can infect a new host, typically pigs.

3. **Development in the Intermediate Host**: After ingestion by pigs, the onchosphere transforms into a different larval form. This transformation occurs in the gut of the pig, where the onchosphere develops further.

4. **Identify the Larval Form**: The larva that develops from the onchosphere in the pig is known as cysticercus. This stage is also referred to as the "bladder worm."

5. **Significance of Cysticercus**: The cysticercus can cause the disease cysticercosis in humans if the larvae are ingested, leading to serious health issues, including neurological problems.

6. **Conclusion**: Therefore, the correct answer to the question is that the larva or embryo which develops from the onchosphere of the tapeworm is called **cysticercus**.

### Final Answer:
The larva or embryo which develops from the onchosphere of Tapeworm is called **cysticercus**.
