Which of the following is a true fruit?

Options

A. Apple
B. Cashew
C. Strawberry
D. Mango

Explanation

To determine which of the following options is a true fruit, we need to understand the concept of true fruits and how they are formed. A true fruit develops solely from the ovary of a flower after fertilization, without any additional floral parts contributing to its structure.

### Step-by-Step Solution:

1. **Understanding True Fruits**:
- A true fruit is formed from the ovary of a flower after fertilization. It consists only of the ovary wall and the seeds.

2. **Analyzing the Options**:
- **Apple**: An apple is considered a false fruit (or accessory fruit) because it develops from the thalamus (receptacle) of the flower, not just the ovary.
- **Cashew**: The cashew is also a false fruit. The cashew nut is the seed, and the cashew apple is an accessory fruit formed from the receptacle.
- **Strawberry**: Strawberries are aggregate fruits, meaning they form from multiple ovaries of a single flower, and they also involve the receptacle in their structure.
- **Mango**: A mango is a true fruit because it develops solely from the ovary of the flower.

3. **Conclusion**:
- Among the given options, the mango is the only true fruit as it is formed entirely from the ovary.

### Final Answer:
The true fruit among the options is **Mango**.
