Options

A.
B.
C.
D.

Answer

To solve the question of choosing the correct floral formula based on the provided floral diagram, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Symmetry**:
- The flower is identified as zygomorphic, which means it has bilateral symmetry. This is represented by the symbol for zygomorphic flowers.

2. **Check for Bracts**:
- The diagram shows no bracts present. Therefore, we classify the flower as ebracteate.

3. **Analyze the Sepals (Calyx)**:
- There are five sepals that are fused together. This condition is known as gamosepalous. Therefore, we denote this as K5 (where K represents the calyx and 5 indicates the number of sepals).

4. **Examine the Petals (Corolla)**:
- The flower has five petals arranged in a specific pattern: 1 petal is superior, 2 petals are arranged alternately, and the last 2 petals are fused. This can be represented as C(1 + 2 + 2) with the last two being fused.

5. **Determine the Androecium (Stamens)**:
- The flower has a total of 10 stamens arranged in a 9 + 1 bundle, where the 9 are fused at the base. This is represented as A(9 + 1), where A indicates the stamens.

6. **Identify the Gynaecium (Carpels)**:
- There is one carpel that is unilocular with a single ovule. This is denoted as G1.

7. **Compile the Floral Formula**:
- Now, we can compile all the information into a floral formula format:
- Symmetry: Zygomorphic
- Bisexual: Yes
- Calyx: K5 (fused)
- Corolla: C(1 + 2 + 2) (with the last two fused)
- Androecium: A(9 + 1) (with 9 fused)
- Gynaecium: G1

8. **Match with Options**:
- Compare the compiled floral formula with the provided options to find the correct match.

### Conclusion:
After analyzing the floral diagram and compiling the floral formula, we find that the second option matches all the characteristics we derived from the diagram. Therefore, the correct floral formula is:

**Floral Formula: Zygomorphic, Bisexual, K5, C(1 + 2 + 2), A(9 + 1), G1**
