Which factors affect Blood Alcohol Concentration (BAC)?

The correct option highlights critical factors that influence Blood Alcohol Concentration (BAC). Each element contributes to how alcohol is absorbed, processed, and affects an individual's system.

Firstly, the number of drinks consumed directly increases BAC as more alcohol enters the bloodstream. The speed of consumption also plays a crucial role since drinking rapidly can lead to a quicker rise in BAC, overwhelming the body's ability to metabolize the alcohol.

Gender is another important variable: biological differences typically affect how men and women process alcohol, with women generally having a higher BAC than men after consuming the same amount of alcohol due to lower water content in their bodies. Weight impacts BAC because a heavier individual may have a lower concentration of alcohol in their bloodstream compared to a lighter person after consuming the same number of drinks. Lastly, food intake is significant; consuming food can slow the absorption of alcohol, affecting the overall BAC.

Understanding these factors is essential for recognizing how alcohol consumption can impact safety and performance, particularly when operating a vehicle, such as a motorcycle or moped.
