D

Explanation: 

Detailed explanation-1: -The liver is the primary organ responsible for the detoxification of alcohol. Liver cells produce the enzyme alcohol dehydrogenase which breaks alcohol into ketones at a rate of about 0.015 g/100mL/hour (reduces BAC by 0.015 per hour).

Detailed explanation-2: -Ninety-five percent of alcohol is metabolized in the liver to its final products of water, carbon monoxide and carbohydrates. It is very important to know that the liver can metabolize alcohol with a certain rate, which does not depend on the concentration of alcohol in the blood.

Detailed explanation-3: -Metabolism is simply a process of chemical change and approximately 90-95% of alcohol metabolism occurs in the liver at the hands of an enzyme known as alcohol dehydrogenase. The body uses several different metabolic pathways in its oxidation of alcohol to acetaldehyde to acetic acid to carbon dioxide and water.
