Which of the following is an outcome of fungal activity?

Options

A. Swiss cheese
B. Toddy
C. Curd
D. Streptomycin

Answer

To solve the question "Which of the following is an outcome of fungal activity?", we will analyze each option provided and identify which one is associated with fungi.

### Step-by-Step Solution:

1. **Identify the Options**: First, we need to look at the options given in the question. The options include Swiss cheese, Toddy, Curd, and Streptomycin.

2. **Analyze Swiss Cheese**: Swiss cheese is produced through bacterial fermentation, specifically by the bacteria Propionibacterium. Therefore, Swiss cheese is not an outcome of fungal activity.

3. **Analyze Toddy**: Toddy is an alcoholic beverage derived from the sap of palm trees. It is produced through fermentation, which can involve fungi. This means Toddy is indeed an outcome of fungal activity.

4. **Analyze Curd**: Curd is made through the fermentation of milk by bacteria, particularly Lactobacillus. Thus, curd is not a product of fungal activity.

5. **Analyze Streptomycin**: Streptomycin is an antibiotic that is produced by bacteria, specifically from the genus Streptomyces. Therefore, it is not associated with fungal activity.

6. **Conclusion**: After analyzing all the options, the only product that results from fungal activity is Toddy. Hence, the correct answer is the second option, Toddy.

### Final Answer:
The outcome of fungal activity is **Toddy**.
