Which one of the following fruits is parthenocarpic?

Options

A. Jackfruit
B. Banana
C. Brinjal
D. Apple

Answer

To determine which of the following fruits is parthenocarpic, we need to understand the concept of parthenocarpy. Parthenocarpy is the development of fruit without fertilization, leading to the formation of seedless fruits. Let's analyze the options provided:

1. **Jackfruit**: This fruit typically contains seeds. Therefore, it is not parthenocarpic.

2. **Banana**: Bananas are known to develop without fertilization and are seedless. This makes banana a parthenocarpic fruit.

3. **Brinjal (Eggplant)**: Brinjal also produces seeds when it develops, so it is not parthenocarpic.

4. **Apple**: Apples contain seeds as well, which means they are not parthenocarpic.

Based on this analysis, the fruit that is parthenocarpic is **banana**.

### Step-by-Step Solution:
1. **Understand Parthenocarpy**: Recognize that parthenocarpy refers to the development of fruit without fertilization, resulting in seedless fruits.

2. **Evaluate Each Option**:
- **Jackfruit**: Contains seeds → Not parthenocarpic.
- **Banana**: Seedless → Parthenocarpic.
- **Brinjal**: Contains seeds → Not parthenocarpic.
- **Apple**: Contains seeds → Not parthenocarpic.

3. **Identify the Correct Answer**: The only fruit that is parthenocarpic among the options is **banana**.
