Wine with 24 proof is …… by volume of alcohol.

Options

A. `12%`
B. `24%`
C. `48%`
D. `6%`

Explanation

To solve the question regarding the alcohol content in wine with 24 proof, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Proof**:
- Proof is a measure of the strength of an alcoholic beverage. It is defined as twice the percentage of alcohol by volume in the mixture.

2. **Given Information**:
- The wine has a proof of 24.

3. **Setting Up the Equation**:
- Since proof is defined as twice the percentage of alcohol by volume, we can express this as:
\[ \text{Proof} = 2 \times \text{Percentage of Alcohol by Volume} \]
- Substituting the given proof value:
\[ 24 = 2 \times \text{Percentage of Alcohol by Volume} \]

4. **Solving for Percentage of Alcohol by Volume**:
- To find the percentage of alcohol by volume, we can rearrange the equation:
\[ \text{Percentage of Alcohol by Volume} = \frac{24}{2} \]
- Performing the calculation:
\[ \text{Percentage of Alcohol by Volume} = 12 \]

5. **Conclusion**:
- Therefore, the wine with 24 proof contains **12% by volume of alcohol**.

### Final Answer:
The correct answer is **12%** by volume of alcohol.
