Options

A. Malvaceae
B. Compositae
C. Liliaceae
D. Solanaceae

Answer

To solve the question regarding the presence of a racemose head (Capitulum) and a bicarpillary syncarpus ovary with basal placentation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Key Terms**:
- **Racemose Head (Capitulum)**: This is a type of inflorescence where flowers are arranged on a common receptacle, resembling a single flower head. It is characteristic of certain plant families.
- **Bicarpillary Syncarpus Ovary**: This indicates that the ovary is formed from two fused carpels (bicarpillary) and is syncarpous, meaning the carpels are joined together.
- **Basal Placentation**: This refers to the arrangement of ovules at the base of the ovary.

2. **Identifying the Plant Family**:
- The combination of a racemose head and bicarpillary syncarpus ovary with basal placentation is notably found in the **Asteraceae** family, also known as the composite family.

3. **Characteristics of Asteraceae**:
- The Asteraceae family is characterized by the presence of a specialized inflorescence called a capitulum, which consists of numerous florets.
- The flowers in this family often have a complex structure, with the pistils typically having two fused carpels, confirming the bicarpillary syncarpous condition.

4. **Conclusion**:
- Based on the characteristics described, the correct answer to the question is the **Asteraceae family**.

### Final Answer:
The presence of a racemose head (Capitulum) and bicarpillary syncarpus ovary with basal placentation belongs to the **Asteraceae family**.
