Slime moulds in the division myxomycota (true slime moulds) have:

Options

A. pseudoplasmodia
B. feeding stages consisting of solitary, individual cells
C. spores that develop into free-living amoeboid cells
D. spores that develop into flagellated gametes

Explanation

To solve the question regarding slime molds in the division Myxomycota (true slime molds), we will analyze each option provided and determine which one accurately describes the characteristics of these organisms.

### Step-by-Step Solution:

1. **Understanding Myxomycota**:
- Myxomycota, or true slime molds, are unique organisms that have a complex life cycle involving both a feeding stage and a reproductive stage.

2. **Analyzing the Options**:
- **Option 1: Pseudoplasmodia**:
- This option suggests that slime molds have pseudoplasmodia. However, true slime molds form a plasmodium, which is a multinucleate mass of protoplasm, not a pseudoplasmodium. Therefore, this option can be ruled out.

- **Option 2: Feeding stages consisting of solitary individual cells**:
- This option implies that the feeding stage of slime molds consists of individual cells. In reality, the feeding stage of Myxomycota is a plasmodium, which is a single mass containing multiple nuclei, rather than solitary cells. Thus, this option is also incorrect.

- **Option 3: Spores that develop into free-living amoeboid cells**:
- This option states that the spores develop into free-living amoeboid cells. While spores are produced, they do not develop into free-living amoeboid cells in Myxomycota. Therefore, this option is ruled out as well.

- **Option 4: Spores that develop into flagellated gametes**:
- This option indicates that the spores develop into flagellated gametes. This is accurate, as the spores produced by the fruiting bodies of slime molds do indeed develop into flagellated gametes during their life cycle.

3. **Conclusion**:
- After analyzing all the options, the correct answer is **Option 4: Spores that develop into flagellated gametes**.

### Final Answer:
**Spores that develop into flagellated gametes.**
