In which of the following plants, in a flower only 3rd whorl of floral organs are fused with 2nd whorl of floral organs?

Options

A. Mustard
B. Bean
C. Pea
D. Brinjal

Answer

To solve the question regarding which plant has its third whorl of floral organs fused with the second whorl of floral organs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Floral Whorls**:
- A flower consists of four main whorls:
- The outermost whorl is the **sepals** (1st whorl).
- The second whorl is the **petals** (2nd whorl).
- The third whorl is the **androecium** (stamens) (3rd whorl).
- The innermost whorl is the **gynoecium** (carpels) (4th whorl).

2. **Identify the Whorls in the Question**:
- The question specifies that we need to find a plant where the **third whorl (androecium)** is fused with the **second whorl (petals)**. This means we are looking for a flower where the petals and stamens are joined together.

3. **Evaluate the Given Options**:
- The options provided are:
- Mustard
- Beans
- Pea
- Brinjal

4. **Analyze Each Option**:
- **Mustard**: In mustard flowers, sepals and petals are distinct and not fused.
- **Beans**: In bean flowers, sepals and petals are also separate.
- **Pea**: In pea flowers, the sepals and petals are not fused.
- **Brinjal**: In brinjal flowers, the sepals and petals are fused together, indicating that the second and third whorls are joined.

5. **Conclusion**:
- Based on the analysis, the only plant where the second whorl (petals) and third whorl (androecium) are fused is **Brinjal**.

### Final Answer:
The plant in which the third whorl of floral organs is fused with the second whorl of floral organs is **Brinjal**.
