The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks in which group of fungi sexual reproduction is absent. 2. **Analyzing the Options**: - **Option 1: Deuteromycetes**: Known as the "imperfect fungi," Deuteromycetes primarily reproduce asexually. They do not have a known sexual reproductive stage, making them a strong candidate for the answer. - **Option 2: Phycomycetes**: This group can reproduce both sexually and asexually. Therefore, sexual reproduction is present in this group. - **Option 3: Ascomycetes**: This group also reproduces both sexually and asexually. Thus, sexual reproduction is present here as well. - **Option 4: Basidiomycetes**: Similar to the previous groups, Basidiomycetes can reproduce both sexually and asexually, indicating that sexual reproduction is also present in this group. 3. **Conclusion**: After analyzing all options, it is clear that sexual reproduction is absent only in **Deuteromycetes**. 4. **Final Answer**: The correct answer is **Deuteromycetes**.
