To answer the question regarding the encapsulated embryo present over the scolex of a tapeworm, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Tapeworms**:
- Tapeworms, which belong to the class Cestoda, have a structure known as the scolex. The scolex is the head region that attaches to the host's intestine.

2. **Identifying the Embryo**:
- The encapsulated embryo that is found on the scolex of a tapeworm is crucial for its life cycle. This structure is responsible for the larval stage of the tapeworm.

3. **Terminology**:
- The encapsulated embryo is scientifically referred to as "cysticercus." This term describes the larval form of the tapeworm that develops in the intermediate host (usually pigs).

4. **Alternative Name**:
- The cysticercus is also commonly known as "bladderworm" due to its appearance, which resembles a bladder.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the encapsulated embryo present over the scolex of a tapeworm is called both "cysticercus" and "bladderworm."

6. **Final Answer**:
- The correct option is both B (bladderworm) and C (cysticercus), which corresponds to option number 4.
