D. Asteraceae.

Answer

To determine which plant family has the largest number of genera and species, we will analyze the given options: Malvaceae, Liliaceae, Brassicaceae, and Asteraceae.

### Step-by-Step Solution:

1. **Identify the Families**: We have four plant families to consider:
- Malvaceae
- Liliaceae
- Brassicaceae
- Asteraceae

2. **Research Each Family**: We need to look at the number of genera and species in each family. This information is typically available in botanical databases or textbooks.

3. **Examine Asteraceae**:
- The Asteraceae family, also known as the composite or sunflower family, is known for its vast diversity.
- It consists of approximately **32,913 accepted species** and **1,911 genera**.
- It also includes **13 subfamilies**, indicating a high level of diversity.

4. **Compare with Other Families**:
- **Malvaceae**: While it is a significant family, it does not match the species count of Asteraceae.
- **Liliaceae**: This family is also diverse but falls short in terms of the number of species compared to Asteraceae.
- **Brassicaceae**: Known for crops like cabbage and mustard, it has fewer species than Asteraceae.

5. **Conclusion**: After comparing the number of genera and species in each family, it is clear that the **Asteraceae family** has the largest number of genera and species among the options provided.

### Final Answer:
The family with the largest number of genera and species of plants is **Asteraceae**.
