Yeast is used in the production of ________.

Options

A. sugar
B. alcohol
C. hydrochloric acid
D. oxygen

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about yeast, which is a single-celled eukaryotic organism. This means it consists of one cell that has a defined nucleus and other organelles.

2. **Understand Yeast's Function**: Yeast is known for its role in fermentation. It can convert sugars into alcohol and carbon dioxide.

3. **Fermentation Process**: During fermentation, yeast consumes sugars (like glucose) and, in the absence of oxygen, produces alcohol and carbon dioxide as byproducts.

4. **Conclusion**: Based on the fermentation process, we conclude that yeast is primarily used in the production of alcohol.

**Final Answer**: Yeast is used in the production of **alcohol**.
