Which of the following is a key factor that influences BAC?

A: Height

B: eating certain foods

C: Body weight

D: All of the above

The correct answer is option C. “Bodyweight.”

## Why option A is incorrect:

Blood alcohol concentration depends on gender, age, metabolism, and body weight. It does not rely on the height of the person; therefore, option A is incorrect.

## Why option B is incorrect:

Blood alcohol concentration depends on gender, age, and body weight. It does not rely on the consumption of certain foods. Therefore, option B is incorrect.

## Why option D is incorrect:

As the correct option is C, therefore, all other options cannot be right.

### Explanation:

The key factor that influence BAC is body weight. The less the bodyweight of a person, the more will be alcohol concentration in the bloodstream. Due to less amount of body weight, the alcohol concentration will affect BAC and body.

Alcohol consumption depends on body type. The heavier you are, the less will be its influence. The reason behind this fact is that persons with more massive bodies have more water content in their bodies as compared to thinner individuals. Because of the higher amount of water in the body, the alcohol dilutes quickly, therefore, reducing their BAC. Thus, even if they drink the same amount of alcohol, the individual with higher body weight will have lower BAC is compared to the person with lower body weight.

### Blood Alcohol Concentration:

BAC stands for Blood Alcohol Concentration. It is the measure of the concentration of alcohol in the bloodstream of human beings. The key factors which influence BAC are the following:

• The content and amount of alcohol
• Gender; females have likely higher BAC than males.
• Bodyweight.
• Food intake
• Duration (the faster is the consumption of alcohol, the higher will be the BAC)

Thus, to conclude, the critical factor which influence BAC is the bodyweight of the person.
