B. Cyathium
C. Spadix
D. Capitulum

Answer

**Step-by-Step Solution:**

1. **Understanding Inflorescence**: Inflorescence refers to the arrangement of flowers on a floral axis. It can take various forms depending on the species of the plant.

2. **Identifying Types of Inflorescence**: There are several types of inflorescence, including Hypanthium, Cyathium, Spadix, and Capitulum. Each type has distinct characteristics.

3. **Analyzing Hypanthium**: In a Hypanthium, the peduncle is modified into a cup-like structure, and while it may contain female flowers, it does not specifically feature a single female flower.

4. **Examining Cyathium**: A Cyathium is a unique type of inflorescence characterized by having a single female flower surrounded by multiple male flowers. This makes it special and directly answers the question.

5. **Considering Spadix**: A Spadix is a type of racemose inflorescence that is covered by a spathe. It can contain multiple flowers and does not focus on having a single female flower.

6. **Reviewing Capitulum**: The Capitulum inflorescence consists of many closely packed flowers that may appear as a single flower (like in sunflowers). However, it does not have a single female flower.

7. **Conclusion**: The inflorescence type that features a single female flower is the Cyathium.

**Final Answer**: A single female flower is a feature of **Cyathium** inflorescence.
