Options

A. calyx, corolla, androecium and gynoecium
B. calyx, corolla, gynoecium and androecium
C. gynoecium, androecium, corolla and calyx
D. androecium, gynoecium, corolla and calyx.

Answer

To determine the arrangement of floral whorls in a typical complete, bisexual, and hypogynous flower from the outermost to the innermost, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Floral Whorls**: A complete flower consists of four main floral whorls: calyx, corolla, androsium, and gynosium. Each of these whorls has a specific role in the structure and function of the flower.

2. **Identifying the Outermost Whorls**: The outermost whorls of a flower are the calyx and corolla.
- **Calyx**: This is the outermost whorl, made up of sepals, which protect the flower in its bud stage.
- **Corolla**: This is the next whorl, made up of petals, which attract pollinators.

3. **Identifying the Innermost Whorls**: The innermost whorls are the androsium and gynosium.
- **Androsium**: This whorl consists of stamens (male reproductive organs) that produce pollen.
- **Gynosium**: This is the innermost whorl, consisting of carpels (female reproductive organs) that house the ovules.

4. **Arranging the Whorls**: Based on the above identification, the arrangement of floral whorls from the outermost to the innermost is:
- **Calyx** (outermost)
- **Corolla**
- **Androsium**
- **Gynosium** (innermost)

5. **Conclusion**: Therefore, the correct arrangement of floral whorls in a typical complete, bisexual, and hypogynous flower is:
- **Calyx → Corolla → Androsium → Gynosium**.

### Final Answer:
Calyx, Corolla, Androsium, Gynosium.
