Choose correct option w.r.t members of deuteromycetes :

Options

A. Have branched and coenocytic mycelium
B. Have sexual or vegetative phase
C. Possess perfect and asexual stage
D. Are decomposers of litter

Answer

To solve the question regarding the members of Deuteromycetes, we will analyze each option provided and determine which one is correct based on the characteristics of Deuteromycetes.

### Step-by-Step Solution:

1. **Understand Deuteromycetes**:
- Deuteromycetes, also known as Fungi Imperfecti, are a group of fungi that do not have a known sexual reproductive stage. They primarily reproduce asexually through conidia.

2. **Evaluate Option 1**:
- **Option 1**: "Have coenocytic mycelium."
- This option is incorrect because coenocytic mycelium is a characteristic of Phycomycetes (like Zygomycetes), not Deuteromycetes.

3. **Evaluate Option 2**:
- **Option 2**: "Have sexual or vegetative phase."
- This option is correct. Members of Deuteromycetes can exhibit both asexual reproduction (vegetative phase) and may have a sexual phase, although it is not well-defined or observed.

4. **Evaluate Option 3**:
- **Option 3**: "Possess perfect and the sexual stage."
- This option is incorrect. The term "perfect stage" refers to the sexual reproductive stage, which is not applicable to Deuteromycetes as they are characterized by the absence of a known sexual stage.

5. **Evaluate Option 4**:
- **Option 4**: "Are decomposers."
- While many fungi, including Deuteromycetes, can act as decomposers, this statement is too broad and does not specifically define Deuteromycetes.

6. **Conclusion**:
- After evaluating all options, the correct answer is **Option 2**: "Have sexual or vegetative phase."

### Final Answer:
The correct option regarding members of Deuteromycetes is **Option 2**.
