Radial symmetry is found in the flowers of

Options

A. Brassica
B. Trifolium
C. Pisum
D. Cassia

Answer

To determine which flowers exhibit radial symmetry, we need to understand the concept of floral symmetry and the classifications of flowers based on their symmetry.

### Step-by-Step Solution:

1. **Understanding Floral Symmetry**:
- Floral symmetry refers to the arrangement of floral organs around the axis of a flower.
- Flowers can be classified based on their symmetry into three categories: actinomorphic (radial symmetry), zygomorphic (bilateral symmetry), and asymmetric.

2. **Identifying Radial Symmetry**:
- A flower is said to have radial symmetry (actinomorphic) if it can be divided into two equal halves by multiple vertical planes. This means that the flower looks the same from different angles.
- Examples of flowers with radial symmetry include mustard (Brassica), datura, and chili.

3. **Analyzing the Given Options**:
- The options provided are:
- A) Cassia
- B) Trifolium
- C) Phyton
- D) Cassia (appears twice, likely a typo)
- We need to identify which of these options has radial symmetry.

4. **Evaluating Each Option**:
- **Cassia**: This flower is zygomorphic, meaning it has bilateral symmetry, not radial.
- **Trifolium**: Also exhibits bilateral symmetry (zygomorphic).
- **Phyton**: Not a commonly recognized flower in this context, but typically would not be radial.
- **Cassia**: Again, as mentioned, it is zygomorphic.

5. **Conclusion**:
- Based on the analysis, none of the options provided exhibit radial symmetry. However, mustard (Brassica) is a clear example of a flower with radial symmetry.
- Therefore, the correct answer to the question regarding which flowers exhibit radial symmetry is not listed among the options provided.

### Final Answer:
None of the options (A, B, C, D) exhibit radial symmetry. A correct example of a flower with radial symmetry is Brassica (mustard).
