D. Asteraceae

Answer

To determine from which plant family coffee and quinine are obtained, we can analyze the options given:

1. **Leguminosae**: This family, also known as the legume, pea, or bean family, includes plants that produce pods. While this family is important for various crops, it is not known for coffee or quinine.

2. **Rubiaceae**: This family is known for flowering plants and includes the coffee plant. Additionally, quinine is derived from the bark of the cinchona tree, which also belongs to this family. Therefore, Rubiaceae is significant for both coffee and quinine.

3. **Poaceae**: Known as the grass family, this family includes many monocots that are primarily food providers (like cereals). However, it does not include coffee or quinine.

4. **Asteraceae**: This family is known for its beautiful flowering plants, such as marigolds and dahlias. It does not produce coffee or quinine.

Based on this analysis, the correct answer is **Rubiaceae**, as both coffee and quinine are obtained from plants in this family.

### Step-by-Step Solution:
1. **Identify the plant families**: Look at the options provided: Leguminosae, Rubiaceae, Poaceae, and Asteraceae.
2. **Analyze Leguminosae**: Recognize that this family is known for legumes and does not include coffee or quinine.
3. **Analyze Rubiaceae**: Note that this family includes the coffee plant and the cinchona tree, which produces quinine.
4. **Analyze Poaceae**: Understand that this family consists mainly of grasses and does not provide coffee or quinine.
5. **Analyze Asteraceae**: Acknowledge that this family is known for flowering plants but does not include coffee or quinine.
6. **Conclusion**: Based on the analysis, conclude that coffee and quinine are obtained from the **Rubiaceae** family.
