Answer

To solve the question of selecting the correct match, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Pollination Types**:
- Pollination is the transfer of pollen grains from the anther to the stigma of a flower.
- There are two main types of pollination:
- **Self-pollination**: Pollen transfer occurs within the same flower.
- **Cross-pollination**: Pollen transfer occurs between different flowers.

2. **Analyzing the Options**:
- **Option A**: Viola, Comelina, Xenogamous flower
- **Xenogamous** refers to cross-pollination. Viola is known for self-pollination, so this match is incorrect.

- **Option B**: Viola, Oxalis, Clistogamous flower
- **Clistogamous** flowers are closed flowers that primarily self-pollinate. Both Viola and Oxalis are known to have clistogamous flowers. This match is correct.

- **Option C**: Tomato, Chili, Clistogamous flower
- Tomatoes and chilies are not clistogamous; they are typically cross-pollinating flowers. This match is incorrect.

- **Option D**: Capsula, Brassica, Chesmogamous flower
- **Chesmogamous** refers to flowers that are open and allow for cross-pollination. While Brassica can have chasmogamous flowers, Capsula is not a commonly recognized term in this context. This match is also likely incorrect.

3. **Conclusion**:
- After analyzing all options, the correct match is **Option B: Viola, Oxalis, Clistogamous flower**.

### Final Answer:
**The correct match is B: Viola, Oxalis, Clistogamous flower.**
