Which of the following is a true fruit ?

Options

A. Apple
B. Pear
C. Cashewnut
D. Coconut

Explanation

To determine which of the following options is a true fruit, we need to understand the definitions and classifications of fruits. Let's analyze each option step by step.

### Step 1: Understand the Definitions
- **True Fruit**: A fruit that develops directly from the ovary after fertilization.
- **False Fruit (Pseudocarp)**: A fruit that develops from parts of the flower other than the ovary, often involving the thalamus.
- **Parthenocarpic Fruit**: A fruit that develops from the ovary without fertilization, resulting in seedless fruits.

### Step 2: Analyze Each Option
1. **Apple**:
- An apple develops from the thalamus as well as the ovary. Therefore, it is classified as a false fruit.

2. **Pear**:
- Pears are also pome fruits that develop from a fleshy thalamus. Thus, they are considered false fruits or pseudocarps.

3. **Cashew Nut**:
- The cashew nut develops directly from the ovary and is classified as a true fruit (eucarp). It has a monocarpillary superior ovary, meaning it develops from a single carpel and is not dependent on the thalamus for its formation.

4. **Coconut**:
- The coconut fruit does not develop solely from the ovary; it involves the endosperm and parts of the embryo. Therefore, it is also classified as a false fruit.

### Step 3: Conclusion
Based on the analysis, the only option that qualifies as a true fruit is **Cashew Nut**.

### Final Answer
**Cashew Nut** is the true fruit among the options provided.
