C. Basal
D. Parietal

Answer

### Step-by-Step Solution:

1. **Understanding Placentation**:
- Placentation refers to the arrangement of ovules within the ovary of a flower. It is crucial to understand this concept as it helps in identifying different types of placentation in various plant families.

2. **Identifying the Family**:
- The question specifically asks about the Malvaceae family. A well-known example of a plant in this family is the China rose (Hibiscus rosa-sinensis).

3. **Types of Placentation**:
- There are several types of placentation including:
- Axile
- Marginal
- Basal
- Parietal

4. **Determining the Type of Placentation in Malvaceae**:
- In the Malvaceae family, the type of placentation observed is **axile placentation**. This means that the ovules are attached to a central column (the placenta) within a multilocular ovary.

5. **Comparing with Other Types**:
- To clarify:
- **Marginal placentation** is found in legumes (Fabaceae).
- **Basal placentation** is seen in plants like sunflowers and marigolds.
- **Parietal placentation** is observed in mustard and ajwain.

6. **Conclusion**:
- Therefore, the correct answer to the question regarding the type of placentation in Malvaceae is **axile placentation**.
