A. Agaricus and Aspergillus
B. Rhizopus and yeast
C. Morchella and saccharomyces
D. Mucor and yeast

Answer

To solve the question of identifying which option contains fungi that belong to the same class, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Classes of Fungi**:
- Fungi are classified into various classes based on their characteristics. Some common classes include Eurotiomycetes, Zygomycetes, Saccharomycetes, and Phycomycetes.

2. **Analyze the First Option (Agaricus and Aspergillus)**:
- **Agaricus**: This fungus belongs to the class **Eurotiomycetes**.
- **Aspergillus**: This fungus also belongs to the class **Eurotiomycetes**.
- **Conclusion**: Both Agaricus and Aspergillus belong to the same class (Eurotiomycetes).

3. **Analyze the Second Option (Rhizopus and Yeast)**:
- **Rhizopus**: This fungus belongs to the class **Zygomycetes**.
- **Yeast (commonly Saccharomyces)**: This fungus belongs to the class **Saccharomycetes**.
- **Conclusion**: Rhizopus and yeast do not belong to the same class.

4. **Analyze the Third Option (Marcella and Saccharomyces)**:
- **Marcella**: This fungus belongs to the class **Phycomycetes**.
- **Saccharomyces**: This fungus belongs to the class **Saccharomycetes**.
- **Conclusion**: Marcella and Saccharomyces do not belong to the same class.

5. **Analyze the Fourth Option (Mucor and Yeast)**:
- **Mucor**: This fungus belongs to the class **Mucoromycetes**.
- **Yeast (commonly Saccharomyces)**: This fungus belongs to the class **Saccharomycetes**.
- **Conclusion**: Mucor and yeast do not belong to the same class.

6. **Final Conclusion**:
- The only option where both fungi belong to the same class is the **first option (Agaricus and Aspergillus)**, as both belong to the class **Eurotiomycetes**.

### Answer:
The correct answer is **Option 1: Agaricus and Aspergillus**.
