A. Clostridium botulinum
B. Lauconostoc citrovorum
C. Saccharomyces cerevisiae
D. Torulopsis utilis.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which organism produces alcohol. We need to evaluate the given options to identify the correct one.

2. **Analyzing the Options**:
- **Clostridium botulinum**: This is a pathogenic bacterium that causes botulism. It is not used for alcohol production.
- **Leuconostoc citroworm**: This is a genus of lactic acid bacteria, primarily known for their probiotic properties. They do not produce alcohol.
- **Saccharomyces cerevisiae**: This is a species of yeast (fungi) known for its role in fermentation, where it converts glucose into alcohol. This is a key organism in the production of alcoholic beverages.
- **Tauropsis utilis**: This is another type of fungus, but it is primarily used as a flavoring agent and not for alcohol production.

3. **Identifying the Correct Answer**: Among the options, **Saccharomyces cerevisiae** is the only organism that is known for producing alcohol through the process of fermentation.

4. **Conclusion**: The correct answer to the question "Which one produces alcohol?" is **Saccharomyces cerevisiae**.
