D. Banana

Answer

To determine which of the following is a pseudocarp among the options apple, guava, tomato, and banana, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Pseudocarp**:
- A pseudocarp, also known as a false fruit, is a type of fruit that is formed not solely from the ovary of the flower but also involves other accessory parts of the flower, such as the thalamus or receptacle.

2. **Analyze Each Option**:
- **Apple**: The fleshy part of the apple is formed from the thalamus, which grows around the ovary. Therefore, it qualifies as a pseudocarp.
- **Guava**: The fruit of guava develops primarily from the ovary and is not formed from accessory parts, so it is not a pseudocarp.
- **Tomato**: The tomato is a true fruit that develops from the ovary of the flower and does not involve accessory parts, making it not a pseudocarp.
- **Banana**: The banana is also a true fruit that develops from the ovary and does not involve accessory parts, so it is not a pseudocarp.

3. **Conclusion**:
- Based on the analysis, the only fruit that qualifies as a pseudocarp from the given options is the **apple**.

### Final Answer:
- **Apple** is a pseudocarp.
