Hexacanth is acttivated by

Options

A. Bile salts
B. Pancreatic jucie
C. Intestinal juice
D. None

Answer

### Step-by-Step Solution:

1. **Understanding Hexacanth**:
- Hexacanth refers to the larval stage of the pork tapeworm (Taenia solium). It is important to recognize that this stage is crucial for the tapeworm's lifecycle.

2. **Lifecycle Context**:
- The pork tapeworm is an endoparasite that primarily resides in the intestines of humans. It can also infect pigs, which is a key part of its lifecycle.

3. **Entry into the Host**:
- The tapeworm enters pigs through the ingestion of contaminated food, often garbage or human excreta that contain onchospheres (the larval form).

4. **Activation of Hexacanth**:
- Once the onchospheres are ingested, they reach the intestine of the pig. The shell of the onchosphere dissolves, releasing the hexacanth larva.

5. **Role of Bile Salts**:
- The activation of the hexacanth larva occurs in the presence of bile salts. These salts are essential for the larva to become active and continue its development.

6. **Final Development**:
- After activation by bile salts, the hexacanth larva migrates to the muscles of the pig, where it develops into cysticercus (the larval cyst stage).

7. **Conclusion**:
- Based on the information discussed, the correct answer to the question "Hexacanth is activated by" is **bile salts**.

### Final Answer:
Hexacanth is activated by **bile salts**.
