Options

A. Ascomycetes
B. Phycomycetes
C. Schizomycetes
D. Zygomycetes

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: The question asks about Penicillium and yeast. Both of these are types of fungi.

2. **Classify the Fungi**: Fungi are classified into different classes. The relevant classes mentioned are Ascomycetes, Phycomycetes, Schizomycetes, and Zygomycetes.

3. **Understand Ascomycetes**: Ascomycetes is a class of fungi that is characterized by the formation of spores in sac-like structures called asci. This class includes many well-known fungi, including Penicillium and yeast.

4. **Check Characteristics of Other Classes**:
- **Phycomycetes**: Considered the most primitive fungi and often referred to as algal fungi.
- **Schizomycetes**: Initially thought to be simple fungi, but more closely related to lower algal groups.
- **Zygomycetes**: Characterized by the formation of sexual spores known as zygospores.

5. **Conclusion**: Since both Penicillium and yeast are known to belong to the class Ascomycetes due to their characteristics of forming spores in asci, the answer is Ascomycetes.

**Final Answer**: Penicillium and yeast belong to the class Ascomycetes.
