Select the sac fungus

Options

A. Albugo
B. Agaricus
C. Neurospora
D. Mucor

Answer

To solve the question of selecting the sac fungus from the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Fungi**:
- Fungi are classified into different groups based on their reproductive structures. The main classes include Ascomycetes (sac fungi), Basidiomycetes, and Phycomycetes.

2. **Identify the Characteristics of Ascomycetes**:
- Ascomycetes, commonly known as sac fungi, typically have a unique reproductive structure called an ascus, where sexual spores (ascospores) are produced. They can be unicellular (like yeast) or multicellular (like Penicillium).

3. **Examine the Options Provided**:
- The options given are:
- A. Albugo
- B. Agaricus
- C. Neurospora
- D. Mucor

4. **Analyze Each Option**:
- **Albugo**: This is a member of Phycomycetes, not Ascomycetes. Therefore, it is not a sac fungus.
- **Agaricus**: This belongs to the Basidiomycetes class, which includes mushrooms. It is also not a sac fungus.
- **Neurospora**: This is a member of Ascomycetes and is indeed a sac fungus. It is also used in genetic studies.
- **Mucor**: This is another member of Phycomycetes and is not a sac fungus.

5. **Conclusion**:
- Based on the analysis, the only option that is a sac fungus (Ascomycetes) is **Neurospora**.

### Final Answer:
The sac fungus among the options provided is **Neurospora**.
