Answer: (A)

Verified step by step guidance

1. Understand that when alcohol enters the body, it is distributed through the bloodstream and needs to be eliminated to reduce its effects.
2. Recognize that the body eliminates alcohol through several pathways: metabolism by the liver, exhalation through the lungs, sweating through the skin, and filtration by the kidneys.
3. Identify that the primary and most efficient method for eliminating alcohol is through metabolic processes, mainly occurring in the liver where enzymes break down alcohol into less harmful substances.
4. Note that while exhalation, sweating, and kidney filtration do contribute to alcohol elimination, their roles are minor compared to the liver's metabolism.
5. Conclude that the key factor responsible for eliminating alcohol from the body is the liver's metabolic processes.
