C. Eucalyptus
D. Azadirachta.

Answer

To answer the question "Mycorrhizal association occurs in Pinus, Ficus and which of the other plants?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Mycorrhizal Association**: Mycorrhiza refers to the symbiotic association between fungi and the roots of higher plants. This relationship is mutually beneficial, meaning both the fungi and the plants gain advantages.

2. **Identify the Benefits**:
- The fungi assist in the absorption of water and essential minerals from the soil, which is facilitated by the extensive network of fungal hyphae that increase the surface area for absorption.
- In return, the plants provide carbohydrates (food) produced through photosynthesis to the fungi.

3. **Recognize Common Plants with Mycorrhizal Associations**:
- Mycorrhizal associations are commonly found in gymnosperms (like Pinus) and some angiosperms (like Ficus).
- Examples of other plants that exhibit mycorrhizal associations include Eucalyptus, Betula, Populus, Fagus, and Shoria.

4. **Evaluate the Options**:
- From the information provided, we can conclude that Eucalyptus is a suitable example of a plant that has a mycorrhizal association alongside Pinus and Ficus.

5. **Select the Correct Answer**:
- Therefore, the answer to the question is Eucalyptus.

### Final Answer:
Mycorrhizal association occurs in Pinus, Ficus, and Eucalyptus.
