Which one of the following is used in the manufacture of alcohol?

Options

A. Bacteria
B. Water molds
C. Yeasts
D. Slime molds

Answer

To solve the question "Which one of the following is used in the manufacture of alcohol?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: First, we need to look at the options provided in the question. Although the options are not listed here, we can assume they include various microorganisms.

2. **Understand Alcohol Production**: Alcohol is primarily produced through fermentation, which is a metabolic process that converts sugar to acids, gases, or alcohol.

3. **Identify the Key Organism**: The key organism involved in the production of alcohol is yeast. Specifically, the species *Saccharomyces cerevisiae* is commonly used in the fermentation process to produce alcohol.

4. **Explain the Fermentation Process**: During fermentation, yeast converts sugars (such as glucose) into ethanol (alcohol) and carbon dioxide (CO2) under anaerobic conditions (absence of oxygen).

5. **Evaluate Other Options**:
- **Bacteria**: While some bacteria can produce alcohol, they are not the primary organisms used for commercial alcohol production.
- **Water Mold**: This belongs to the kingdom Fungi but is not used in alcohol production.
- **Slime Mold**: This belongs to the kingdom Protista and is not involved in alcohol fermentation.

6. **Conclusion**: Based on the information gathered, the organism used in the manufacture of alcohol is yeast, specifically *Saccharomyces cerevisiae*.

### Final Answer:
The correct answer is **yeast** (specifically *Saccharomyces cerevisiae*).
