In the liver, the order of metabolism for the fuel sources typically follows a specific hierarchy due to their energy yield and the body's needs. When all four of the listed fuel sources are present simultaneously, the body will prioritize:
1. **Alcohol**: The liver metabolizes alcohol first because it is considered a toxin, and the body prioritizes removing it.
2. **Glucose**: Once alcohol is processed, the liver will then metabolize glucose, which is a readily available source of energy.
3. **Amino acids**: These are used after glucose, particularly when the body needs to synthesize proteins or if there is an energy deficit.
4. **Fatty acids**: These are typically metabolized last, as they are stored for energy rather than used immediately.
Given this hierarchy, the correct answer to your question is:
**Alcohol**
