D. Umbel

Answer

To solve the question regarding the types of flowers that occur in the inflorescence, we will analyze the options provided and identify which inflorescence contains all three types of flowers: male, female, and sterile.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which type of inflorescence has three types of flowers: male, female, and sterile.

2. **Analyze the Options**:
- **Capitulum**: This type of inflorescence usually consists of many small flowers (florets) that can be either all male or all female, but typically does not have all three types of flowers present.
- **Hypanthodium**: This inflorescence is characterized by a pear-shaped structure that has a cavity. In this cavity, female flowers develop at the base, while male flowers develop towards the opening (pore). This inflorescence can also contain sterile flowers, thus having all three types of flowers.
- **Cyanthium**: This type of inflorescence is typical of plants like Euphorbia, where the flowers are grouped in a way that does not typically include all three types (male, female, and sterile).
- **Umbil**: This is not a commonly recognized term in the context of inflorescence types and does not typically refer to a specific type of flower arrangement.

3. **Identify the Correct Answer**: Based on the analysis, the **Hypanthodium** inflorescence is the only one that contains all three types of flowers: male, female, and sterile.

4. **Final Conclusion**: The correct answer to the question is **Hypanthodium**.
