Sexual reproduction in fungi can occur by means of

Options

A. Sporangiospore, oospore and ascospore
B. Zoospore, oospore and ascospore
C. Sporangiospore, ascospore and basidiospore
D. Oospore, ascospore and basidiospore.

Answer

### Step-by-Step Solution:

1. **Understanding Sexual Reproduction in Fungi**:
- Fungi can reproduce sexually through the formation of specialized spores. These spores are produced as a result of the fusion of gametes.

2. **Identifying Types of Sexual Spores**:
- The main types of sexual spores in fungi include:
- **Oospore**: Formed in Oomycetes (water molds).
- **Ascospores**: Produced in Ascomycetes (sac fungi).
- **Basidiospores**: Formed in Basidiomycetes (club fungi).

3. **Reviewing the Options**:
- The question provides several options regarding the types of spores involved in sexual reproduction:
- **Option 1**: Sporangiospores, Oospore, and Ascospores
- **Option 2**: Zoospore, Oospore, and Ascospores
- **Option 3**: Sporangiospores, Ascospores, and Basidiospores
- **Option 4**: Oospore, Ascospores, and Basidiospores

4. **Evaluating Each Option**:
- **Option 1**: Contains sporangiospores, which are asexual spores. Therefore, this option is incorrect.
- **Option 2**: Contains zoospores, which are also asexual spores. Thus, this option is incorrect.
- **Option 3**: Contains sporangiospores, which are asexual spores. Hence, this option is incorrect.
- **Option 4**: Contains Oospore, Ascospores, and Basidiospores, all of which are sexual spores. This option is correct.

5. **Conclusion**:
- The correct answer is **Option 4: Oospore, Ascospores, and Basidiospores**. These are all types of sexual spores produced during sexual reproduction in fungi.
