Items in which of the following pairing are unrelated

Options

A. Ascocarp-Ascogonium
B. Conidiophore-Metulae
C. Basidiocarp-Gills
D. Ascocarp-Archegonium.

Answer

To solve the question regarding which items in the pairings are unrelated, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Analyze the First Pairing: Eschocarp and Eschogonium**
- **Eschocarp**: This is the fruiting body found in Escomycetes, a type of fungi.
- **Eschogonium**: This is the female reproductive part in Escomycetes.
- **Conclusion**: Both terms are related to Escomycetes. Therefore, this pairing is not unrelated.

2. **Analyze the Second Pairing: Conidiophore and Metulla**
- **Conidiophore**: This is a structure in Ascomycetes that produces conidia (spores).
- **Metulla**: This is a branch of the conidiophore.
- **Conclusion**: Both terms are related to Ascomycetes. Therefore, this pairing is not unrelated.

3. **Analyze the Third Pairing: Bacidiocarp and Gills**
- **Bacidiocarp**: This is the fruiting body of Basidiomycetes.
- **Gills**: These are structures found on the underside of the Bacidiocarp where spores are produced.
- **Conclusion**: Both terms are related to Basidiomycetes. Therefore, this pairing is not unrelated.

4. **Analyze the Fourth Pairing: Aescocarp and Archegonium**
- **Aescocarp**: This is the fruiting body in Ascomycetes.
- **Archegonium**: This is the female reproductive structure found in Bryophytes (plants).
- **Conclusion**: These terms belong to different kingdoms (fungi vs. plants). Therefore, this pairing is unrelated.

### Final Answer:
The items in the pairing that are unrelated are **Aescocarp and Archegonium** (Option 4).
