Answer

To answer the question about the nonessential parts of flowers, we need to understand the different components of a flower and categorize them into essential and nonessential parts.

### Step-by-Step Solution:

1. **Identify the Parts of a Flower**:
- A flower consists of various parts, which can be categorized as essential and nonessential.

2. **Define Essential Parts**:
- The essential parts of a flower are involved in reproduction. These include:
- **Androsium**: The male reproductive part, which consists of stamens (the filament and anther where pollen is produced).
- **Gynosium**: The female reproductive part, which consists of the stigma (which receives pollen), style (the tube leading to the ovary), and ovary (which contains ovules).

3. **Define Nonessential Parts**:
- Nonessential parts of a flower do not directly participate in reproduction but serve other functions, such as protection and attraction. The nonessential parts include:
- **Calyx**: Made up of sepals, which protect the flower in its bud stage.
- **Corolla**: Made up of petals, which attract pollinators with their color and fragrance.

4. **Analyze the Options Given**:
- **Option A**: Sepals and petals (Calyx and Corolla) - These are nonessential parts.
- **Option B**: Sepals and carpels - Carpels are part of the gynosium, which is essential.
- **Option C**: Sepals and gynosium - Gynosium is essential.
- **Option D**: Androsium and gynosium - Both are essential.

5. **Conclusion**:
- The correct answer to the question "Nonessential parts of flowers are" is **Option A: Sepals and petals**.
