Answer

To solve the question regarding the correct pairing of alcohol and the substrate from which it is obtained, we will analyze each option provided and identify the correct matches based on fermentation processes.

### Step-by-Step Solution:

1. **Understanding Alcohol Production**:
- Alcoholic beverages are primarily produced through fermentation, which involves the conversion of sugars into alcohol by microorganisms (yeasts, bacteria).
- Different types of alcohol are derived from different substrates (raw materials).

2. **Identifying Common Alcohol Types**:
- **Beer**: Typically made from barley or wheat.
- **Rum**: Generally produced from molasses, a byproduct of sugarcane processing.
- **Whisky**: Usually made from fermented grain mash, which can include barley, corn, rye, and wheat.
- **Vodka**: Can be made from a variety of substrates, but common ones include potatoes and grains.

3. **Analyzing Options**:
- **Option A**: Barley - Whisky
- **Option B**: Barley - Beer
- **Option C**: Molasses - Rum
- **Option D**: Potato - Rum

4. **Matching Alcohol with Substrates**:
- **Beer** is primarily made from **barley** (Option B is correct).
- **Rum** is made from **molasses** (Option C is correct).
- **Whisky** can be made from **barley** (Option A is correct).
- **Vodka** is typically made from **potatoes** (Option D is incorrect because rum is not made from potatoes).

5. **Conclusion**:
- The correct pairings based on the analysis are:
- Beer - Barley
- Rum - Molasses
- Whisky - Barley
- Vodka - Potatoes

### Final Answer:
The correct pairing of alcohol and the substrate from which it is obtained is:
- **Option B**: Beer - Barley
