Question

select the correct answer.
which statement is true about blood alcohol concentration?
a. blood alcohol concentration is affected by factors such as body size and gender
b. drinking coffee and exercising will lower your blood alcohol concentration.
c. the lower the blood alcohol concentration, the more severe the hangover will be.

Explanation:

• Option A: Body size (e.g., larger body has more water to dilute alcohol) and gender (differences in body composition, enzyme activity) affect blood alcohol concentration (BAC), so this is true.
• Option B: Coffee and exercise do not lower BAC; only time (metabolism) or medical intervention (rarely) can reduce BAC.
• Option C: Higher BAC generally leads to more severe hangovers (more alcohol metabolized into toxic byproducts), so this is false.

Answer:

A. Blood alcohol concentration is affected by factors such as body size and gender
