Conjugation Fungi are

Options

A. Oomycetes
B. Zygomycetes
C. Ascomycete
D. Mushrooms.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about conjugation fungi and provides four options: oomycetes, zygomycetes, ascomycetes, and mushrooms.

2. **Analyzing the Options**:
- **Oomycetes**: These are known as water molds and were previously classified as fungi but are now considered fungus-like organisms in the phylum Oomycota. They primarily act as saprophytes or parasites. Therefore, this option is incorrect.

- **Zygomycetes**: This class of fungi is specifically known as conjugation fungi. They reproduce sexually through a process that involves the formation of zygospores, which undergo meiosis to produce haploid spores. This process is known as conjugation, making this option correct.

- **Ascomycetes**: Known as sac fungi, they produce a structure called ascus, which contains sexual spores known as ascospores. This does not relate to conjugation fungi, so this option is incorrect.

- **Mushrooms**: These belong to the phylum Basidiomycetes and are characterized by their umbrella-shaped fruiting bodies. They do not represent conjugation fungi, making this option incorrect.

3. **Conclusion**: Based on the analysis, the correct answer to the question "Conjugation fungi are" is **zygomycetes**.

### Final Answer:
Conjugation fungi are **zygomycetes**.
