C. Complete
D. perfect.

Answer

To determine the flower that contains all four types of floral organs, we need to understand the definitions and characteristics of the options provided:

1. **Identify the Floral Organs**:
- The four types of floral organs in a flower are:
- **Calyx**: The outermost whorl, made up of sepals.
- **Corolla**: The second whorl, made up of petals.
- **Androsium**: The male reproductive part, consisting of stamens.
- **Gynosium**: The female reproductive part, consisting of carpels.

2. **Understanding the Options**:
- **Regular Flower**: These flowers exhibit radial symmetry, meaning they can be divided into equal halves in multiple ways. However, this does not necessarily indicate the presence of all four floral organs.
- **Irregular Flower**: These flowers show bilateral symmetry, meaning they can only be divided into equal halves in one specific way. Like regular flowers, this does not confirm the presence of all four organs.
- **Complete Flower**: This type of flower contains all four floral organs (calyx, corolla, androsium, and gynosium). Therefore, it meets the criteria of having all floral organs present.
- **Perfect Flower**: This flower has both male (androsium) and female (gynosium) reproductive organs. While it may contain some floral organs, it does not necessarily include all four.

3. **Conclusion**:
- Based on the definitions and characteristics of the options, the correct answer is **Complete Flower**. A complete flower is defined as one that has all four types of floral organs.

### Final Answer:
The flower with all four types of floral organs is a **Complete Flower**.
