B. Funaria
C. Rhizopus
D. Brassica.

Answer

To determine which among the given plants has archegonium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Archegonium**: Archegonium is a female reproductive structure found in certain groups of plants. It is crucial to know which plant groups possess this structure.

2. **Identify Plant Groups with Archegonium**: Archegonia are present in:
- Bryophytes (e.g., mosses and liverworts)
- Pteridophytes (e.g., ferns)
- Gymnosperms (e.g., conifers)
They are absent in Angiosperms (flowering plants) and Algae.

3. **Analyze the Options**:
- **Option 1: Spirogyra**: This is an algae, and as mentioned, archegonium is absent in algae.
- **Option 2: Funeria**: This is a bryophyte, which does possess archegonium.
- **Option 3: Rhizopus**: This is a fungus, and fungi do not have archegonia.
- **Option 4: Brassica**: This is an angiosperm, and archegonia are absent in flowering plants.

4. **Select the Correct Answer**: Based on the analysis, the only plant that has archegonium is **Funeria** (Option 2).

5. **Conclusion**: Therefore, the correct answer to the question is **Option 2: Funeria**.
