B. viruses
C. microbes
D. prions

Answer

To answer the question "Which of the following is used in preparing cheese?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cheese Production**: Cheese is produced through a fermentation process involving specific microbes. These microbes help in the coagulation of milk proteins and contribute to the flavor and texture of the cheese.

2. **Identifying the Microbes**: One of the key microbes used in the production of Swiss cheese is a bacterium known as **Propionibacterium shermanii**. This bacterium is responsible for the characteristic holes in Swiss cheese due to the production of carbon dioxide during anaerobic respiration.

3. **Analyzing the Options**: If the question provides multiple options, we need to identify which option mentions **Propionibacterium shermanii** or any other relevant microbe used in cheese production.

4. **Selecting the Correct Option**: Based on the information that Swiss cheese is made using **Propionibacterium shermanii**, we can conclude that the correct answer is the option that lists this bacterium or mentions the use of microbes in cheese preparation.

5. **Final Answer**: Therefore, the correct answer to the question is the option that indicates the use of **microbes**, specifically **Propionibacterium shermanii**.
