Options

A. scolex
B. strobila
C. neck
D. the whole body.

Answer

To solve the question regarding the seat of proliferation with fertilized eggs in the uterus of a tapeworm, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Tapeworm Structure**:
- Tapeworms belong to the phylum Platyhelminthes and have a segmented body structure. Each segment is called a proglottid.

**Hint**: Remember that tapeworms are segmented and that each segment has a specific function.

2. **Identifying Proglottids**:
- Proglottids are the segments of the tapeworm that can contain fertilized eggs. Among these, there are special proglottids known as gravid proglottids, which are filled with fertilized eggs.

**Hint**: Focus on the role of proglottids in reproduction for tapeworms.

3. **Understanding Gravid Proglottids**:
- Gravid proglottids are the segments that are packed with fertilized eggs. These segments are regularly detached from the rest of the tapeworm's body.

**Hint**: Consider what happens to the segments filled with eggs after fertilization.

4. **Defining the Process of Detachment**:
- The process by which these gravid proglottids detach is known as apolysis. This is a specific term used in the context of tapeworm reproduction.

**Hint**: Look for terminology related to the reproductive process in tapeworms.

5. **Identifying the Correct Term**:
- The question asks for the term that describes the area where these fertilized eggs are located and regularly detached. This area is referred to as the strobila, which is the entire body of the tapeworm made up of proglottids.

**Hint**: Remember that the strobila refers to the overall structure that contains the proglottids.

### Conclusion:
The correct answer to the question is **strobila**. This term refers to the body of the tapeworm where the proglottids, including those with fertilized eggs, are located and regularly detached.
