The correct option is D Metabolic process in liver
Alcohol is eliminated from the body by various metabolic mechanisms. The liver is responsible for the elimination through metabolism of 95% of ingested alcohol from the body. Alcohol is detoxified and removed from the blood through oxidation. Oxidation prevents the alcohol from accumulating and destroying cells and organs. A healthy liver oxidizes pure ethanol at the rate of about 1/4 to 1/3 of an ounce per hour, which is less than 1 ounce of hard liquor.
Thus, the correct answer is option (D), 'Metabolic process in liver'.
