Which one of the following floral formula represents the mustard plant ?

Options

A. `P_(3+3)C_4A_(3+3)ul(G)(3)`
B. `K_5C_5A_5ul(G)(2)`
C. `K_5C_(1+2+(2))A_((9)+1)ulG1`
D. `K_(2+2)C_4A_(2+4)ul(G(2))`

Answer

To determine which floral formula represents the mustard plant, we need to analyze the characteristics of the mustard plant and its classification within the plant family.

### Step-by-Step Solution:

1. **Identify the Family**:
- The mustard plant belongs to the family **Brassicaceae** (also known as Cruciferae). This is the first step in identifying the floral formula.

**Hint**: Remember that the family classification is crucial for determining floral characteristics.

2. **Understand Floral Parts**:
- In the Brassicaceae family, the floral structure typically includes:
- **Calyx**: 4 sepals
- **Corolla**: 4 petals
- **Androsium**: 6 stamens (arranged in 4 long and 2 short)
- **Gynosium**: 2 carpels, which is a superior ovary.

**Hint**: Familiarize yourself with the basic floral parts and their typical numbers in different families.

3. **Construct the Floral Formula**:
- Based on the above characteristics, the floral formula for the mustard plant can be represented as:
- **Floral Formula**:
- Calyx (C) = 4 (sepals)
- Corolla (K) = 4 (petals)
- Androsium (A) = 4 + 2 (6 stamens)
- Gynosium (G) = 2 (carpels)
- The complete floral formula can be written as: **K4 C4 A4+2 G2**.

**Hint**: Use the notation K (for calyx), C (for corolla), A (for androsium), and G (for gynosium) to construct floral formulas.

4. **Select the Correct Option**:
- Compare the constructed floral formula with the given options in the question. The correct floral formula for the mustard plant will match the characteristics we have identified.

**Hint**: Carefully compare each option with the floral formula you constructed to find the correct match.

### Final Answer:
The floral formula that represents the mustard plant is **K4 C4 A4+2 G2**.
