Answer

To solve the question of selecting the correct match regarding types of flowers and their pollination methods, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Flower Types and Pollination**:
- First, we need to understand the different types of flowers and their pollination methods:
- **Xenogamous Flowers**: These flowers undergo cross-pollination, where pollen from one flower fertilizes another flower.
- **Clistogamous Flowers**: These flowers remain closed and only allow self-pollination, meaning they do not engage in cross-pollination.
- **Chasmogamous Flowers**: These flowers remain open and can undergo both self-pollination and cross-pollination.

2. **Analyzing the Options**:
- **Option A: Viola and Camelina - Xenogamous Flowers**:
- **Analysis**: Viola is known for having clistogamous flowers, while Camelina is not typically classified as xenogamous. Therefore, this option is incorrect.

- **Option B: Viola and Oxalis - Clistogamous Flowers**:
- **Analysis**: Both Viola and Oxalis are known to have clistogamous flowers, which means they only self-pollinate. This option is correct.

- **Option C: Tomato and Chili - Clistogamous Flowers**:
- **Analysis**: Tomato and chili plants are not clistogamous; they are typically chasmogamous flowers. Thus, this option is incorrect.

- **Option D: Capsula and Brassica - Chasmogamous Flowers**:
- **Analysis**: While Brassica is a chasmogamous flower, Capsula does not fit this classification. Therefore, this option is also incorrect.

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

### Final Answer:
The correct match is **Option B: Viola and Oxalis - Clistogamous Flowers**.
