B.
C.
D.

Answer

To determine the floral formula for the Brassicaceae family, we will analyze the characteristics of the flowers belonging to this family. The Brassicaceae family is commonly known as the mustard family, which includes plants like mustard.

### Step-by-Step Solution:

1. **Identify Flower Symmetry**:
- The flowers of the Brassicaceae family are actinomorphic, meaning they can be divided into two equal halves through multiple planes.

**Hint**: Remember that actinomorphic flowers exhibit radial symmetry.

2. **Determine the Flower Structure**:
- The flowers are typically bisexual, meaning they contain both male (stamens) and female (pistils) reproductive structures.

**Hint**: Bisexual flowers are essential for self-pollination and reproduction.

3. **Analyze the Calyx**:
- The calyx consists of 4 sepals, which are usually arranged in a distinct pattern.

**Hint**: Count the number of sepals carefully; they are often green and leaf-like.

4. **Examine the Corolla**:
- The corolla is made up of 4 petals, which are often arranged in a cross shape, giving rise to the common name "crucifer" for this family.

**Hint**: Look for the characteristic cross shape of the petals.

5. **Evaluate the Androecium**:
- The androecium consists of 6 stamens, arranged in a specific pattern of 4 long and 2 short.

**Hint**: Pay attention to the arrangement of stamens; this is a key identifying feature.

6. **Consider the Gynoecium**:
- The ovary is superior and typically has 2 or more locules (chambers), indicating the presence of multiple ovules.

**Hint**: The position of the ovary (superior) is crucial for identifying the family.

7. **Compile the Floral Formula**:
- Based on the observations:
- Calyx: 4 (C)
- Corolla: 4 (K)
- Androecium: 4+2 (A)
- Gynoecium: 2 (G)
- The floral formula can be represented as: **K4 C4 A4+2 G(2)**

**Hint**: Ensure that you represent the number of parts accurately in the floral formula.

### Final Floral Formula for Brassicaceae:
The floral formula for the Brassicaceae family is K4 C4 A4+2 G(2).

### Summary:
- The Brassicaceae family is characterized by actinomorphic, bisexual flowers with a floral formula of K4 C4 A4+2 G(2). This formula highlights the unique arrangement of sepals, petals, stamens, and the structure of the ovary.
