Pseudomycelium occurs in :-

Options

A. Mushroom
B. Mucor
C. Bread mold
D. Yeast

Answer

To determine where pseudomycelium occurs, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pseudomycelium**:
- Pseudomycelium is a type of cellular association. It is important to recognize that it is not a true mycelium but resembles it.

2. **Identifying Organisms**:
- The options provided are:
- A) Mushroom
- B) Mucus
- C) Bread mold
- D) Yeast

3. **Analyzing Each Option**:
- **Mushroom**: This is a type of fungus that forms true mycelium, not pseudomycelium.
- **Mucus**: This is a secretion and does not relate to fungal structures.
- **Bread Mold**: This typically refers to molds like Rhizopus, which also forms true mycelium.
- **Yeast**: Yeast, particularly species like Saccharomyces cerevisiae, can form pseudomycelium. This occurs when yeast cells elongate and remain attached, forming a chain-like structure.

4. **Conclusion**:
- Based on the analysis, pseudomycelium occurs in yeast. Therefore, the correct answer is option D) Yeast.

### Final Answer:
Pseudomycelium occurs in **D) Yeast**.
