Which one of the following is not an example of parthenocarpic fruit ?

Options

A. Apple
B. Persimmon
C. Graperfruit
D. Watermelon

Answer

To determine which of the following is not an example of a parthenocarpic fruit, we need to understand what parthenocarpy means. Parthenocarpy is the natural or artificially induced development of fruit without fertilization, resulting in seedless fruits.

### Step-by-Step Solution:

1. **Define Parthenocarpic Fruits**:
- Parthenocarpic fruits are those that develop without fertilization, leading to the formation of seedless fruits.

2. **Analyze the Given Options**:
- The options provided are:
- A) Apple
- B) Persimmon
- C) Grapefruit
- D) Watermelon

3. **Identify Parthenocarpic Examples**:
- **Persimmon**: This is known to produce parthenocarpic fruits.
- **Grapefruit**: Grapefruit can also develop parthenocarpically.
- **Watermelon**: Watermelon is commonly known to produce seedless varieties through parthenocarpy.

4. **Evaluate Apple**:
- **Apple**: Apples are typically developed from the thalamus (the thickened part of the stem) and not primarily from the ovary. Therefore, apples are considered false fruits and do not develop as parthenocarpic fruits.

5. **Conclusion**:
- Based on the analysis, the fruit that is not an example of a parthenocarpic fruit is **A) Apple**.

### Final Answer:
**A) Apple**
