Which one of the followingt is the most suitable medium for culture of Drosophila melanogaster

Options

A. Moist bread
B. Agar-agar
C. Ripe banana
D. cow dung

Answer

To determine the most suitable medium for the culture of Drosophila melanogaster, also known as the fruit fly, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Drosophila melanogaster is commonly known as the fruit fly. It is widely used in genetic research due to its short life cycle and simple genetic makeup.

2. **Understand the Requirements**: To culture Drosophila, we need a medium that provides the necessary nutrients and environment for the flies to thrive and reproduce.

3. **Evaluate the Options**: The question provides several options for the culture medium. We need to assess each option:
- **Option A: Moist Bread**: While it may provide some nutrients, it is not the ideal medium for Drosophila.
- **Option B: Agar Agar Solution**: This is primarily used for tissue culture and is not suitable for fruit flies.
- **Option C: Ripe Banana**: This is a natural food source for fruit flies and provides the necessary nutrients for their growth and reproduction.
- **Option D: Cow Dung**: This is not a suitable medium for fruit flies as it is more of a habitat for bacteria.

4. **Select the Best Option**: After evaluating all the options, it is clear that ripe banana (Option C) is the most suitable medium for the culture of Drosophila melanogaster.

5. **Conclusion**: Therefore, the correct answer is **ripe banana**, which serves as an excellent culture medium for fruit flies.

### Final Answer:
The most suitable medium for the culture of Drosophila melanogaster is **ripe banana**.
