Options

A. Reserve food
B. Sexual reproduction
C. Flagella
D. Structure of spores

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the basis of traditional classification of fungi. We need to identify the key criteria used in this classification.

2. **Identifying Classification Criteria**: Traditional classification of fungi is primarily based on their reproductive structures and methods. This includes both sexual and asexual reproduction.

3. **Exploring Sexual Reproduction**: In traditional classification, fungi are categorized based on their sexual reproductive structures. The presence of specific reproductive structures is a significant factor.

4. **Categories of Fungi**:
- **Chytridiomycota**: Characterized by the production of motile zoospores.
- **Zygomycota**: Known for forming zygospores during reproduction.
- **Ascomycota**: Identified by the formation of ascospores within sac-like structures called asci.
- **Basidiomycota**: Recognized by the production of basidiospores on club-shaped structures called basidia.
- **Deuteromycota**: This group includes fungi that have lost the ability to reproduce sexually and are often referred to as "imperfect fungi."

5. **Conclusion**: Based on the above classifications, the traditional classification of fungi is primarily based on sexual reproduction.

### Final Answer:
The traditional classification of fungi is based on **sexual reproduction**.
