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, we need to evaluate the options provided: moist bread, agar agar, ripe banana, and cow dung.

### Step-by-Step Solution:

1. **Identify the Organism**: Drosophila melanogaster is commonly known as the fruit fly. It is widely used in genetic research and studies.

2. **Evaluate the Options**:
- **Moist Bread**: While it can serve as a culture medium for some fungi (like Rhizopus), it is not suitable for Drosophila.
- **Agar Agar**: This is primarily used as a solidifying agent in microbiological culture media and is not specifically suited for Drosophila culture.
- **Ripe Banana**: This is a natural food source for fruit flies. Ripe bananas are rich in carbohydrates and sugars, which are essential for the growth and nutrition of Drosophila melanogaster.
- **Cow Dung**: Although cow dung can be used as a substrate in some biological processes, it is not an appropriate medium for culturing Drosophila.

3. **Conclusion**: Based on the evaluation, the most suitable medium for the culture of Drosophila melanogaster is **ripe banana**.

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