Alcohol is quick to find its way to the brain because the central aorta supplies it the brain contains more blood the brain contains more oxygen of the brain's elevated location

Option B, the brain contains more blood

Explanation:

Alcohol in our body is primarily absorbed by the intestine and stomach. Once the alcohol is absorbed it diffuses into the blood stream. As the alcohol completely  diffuses into the blood , it reaches different body parts especially the brain ( as it requires a prominent supply of blood as compared to all other body parts). The alcohol mixed blood when reaches the brain produces hallucination effects and thus, the brain becomes unable to  focus and think

Effects of alcohol are felt once the alcohol diffuse into the blood and reaches different body parts. Thus, option B is correct.
