Zygomorphic flowers are found in:-
(a) Mustard
(b) Gulmohur
(c) China rose
(d) Datura

Options

A. Mustard
B. Gulmohur
C. China rose
D. Datura

Answer

To determine which of the given plants has zygomorphic flowers, we need to understand the definitions of zygomorphic and actinomorphic flowers.

### Step-by-Step Solution:

1. **Understand Flower Symmetry**:
- Flowers can be classified based on their symmetry into two main types:
- **Zygomorphic Flowers**: These flowers cannot be divided into two identical halves. They have unequal parts, meaning that there is only one plane of symmetry.
- **Actinomorphic Flowers**: These flowers can be divided into two identical halves along multiple planes. They have equal floral parts.

2. **Analyze the Options**:
- **(a) Mustard**: Mustard flowers are actinomorphic. They have symmetrical floral parts.
- **(b) Gulmohur**: Gulmohur flowers are zygomorphic. They have unequal petals and can only be divided into two equal halves in one specific way.
- **(c) China Rose**: China rose flowers are actinomorphic. They exhibit symmetry and can be divided into equal halves.
- **(d) Datura**: Datura flowers are also actinomorphic, having symmetrical floral parts.

3. **Identify the Correct Answer**:
- From the analysis, the only plant that has zygomorphic flowers is **Gulmohur** (option B).

### Final Answer:
The correct answer is **(b) Gulmohur**.
