A. leafy gametophyte
B. protonema
C. prothallus
D. peristome

Answer

To answer the question, "The spores produced in the capsule in moss germinate to form a haploid structure called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: Recognize that the question pertains to mosses, which are part of the plant kingdom and specifically belong to the group known as bryophytes.

2. **Identify the Reproductive Structures**: In mosses, spores are produced in a structure called the capsule. This is a key point because it indicates where the spores originate.

3. **Germination of Spores**: When the spores produced in the capsule germinate, they do not directly form the gametophyte. Instead, they first develop into another structure.

4. **Formation of Protonema**: The spores germinate to form a haploid structure known as the protonema. This protonema is a green, filamentous structure that serves as the initial stage in the life cycle of mosses.

5. **Transition to Gametophyte**: After the protonema stage, the moss will eventually develop into the mature gametophyte, which is the main plant body of mosses.

6. **Conclusion**: Therefore, the correct answer to the question is that the spores produced in the capsule in moss germinate to form a haploid structure called the **protonema**.

### Final Answer:
The spores produced in the capsule in moss germinate to form a haploid structure called **protonema**.
