Options

A. Lower part
B. Upper part
C. Middle part
D. Fertile part.

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of the Moss Capsule**:
- The moss capsule is a part of the reproductive structure of mosses. It consists of several sections, including the apophysis, seta, and the spore-producing area.

2. **Identifying the Apophysis**:
- The apophysis is described as a solid, somewhat swollen, and green portion of the capsule. It is specifically noted for its photosynthetic capabilities.

3. **Location of the Apophysis**:
- The apophysis is located at the lower part of the moss capsule. It serves as a transitional area between the capsule and the seta (the stalk).

4. **Function of the Apophysis**:
- The apophysis plays a crucial role in the conduction of water and nutrients. It is involved in the photosynthesis process, which is vital for the moss's energy needs.

5. **Additional Features**:
- Internally, the apophysis is covered by an epidermis, and it is the only part of the capsule that contains stomata, which are essential for gas exchange.

6. **Conclusion**:
- Based on the characteristics and location of the apophysis, the correct answer to the question is that the apophysis in the moss capsule is located in the lower part.

### Final Answer:
The apophysis in the moss capsule is the lower part.
