D. False fruits

Answer

To answer the question "In some plants, thalamus contributes to fruit formation. Such fruits are termed as", we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understand the Thalamus**: The thalamus, or receptacle, is the thickened part of the stem from which the flower organs arise. In some plants, it plays a significant role in fruit development.

2. **Identify the Types of Fruits**:
- **A. Aggregate Fruits**: These fruits form from multiple carpels of a single flower. Examples include blackberry and raspberry. The thalamus does not primarily contribute to these fruits.
- **B. True Fruits**: True fruits develop solely from the ovary of a flower after fertilization. Examples include mango and peach. The thalamus is not involved in the formation of true fruits.
- **C. Parthenocarpic Fruits**: These fruits develop without fertilization, resulting in seedless fruits. Examples include bananas. The thalamus does not contribute to these fruits either.
- **D. False Fruits**: Also known as accessory fruits, these fruits develop from the ovary along with other floral parts, including the thalamus. Examples include apples and figs, where the thalamus is a significant part of the edible fruit.

3. **Conclusion**: Based on the definitions and examples, the correct answer is **D. False fruits**, as these fruits are formed with the contribution of the thalamus along with the ovary.

### Final Answer:
**D. False fruits**
