Which of the following factors affect an individual's absorption of alcohol?

The absorption of alcohol in the body can be significantly influenced by a person's weight. Heavier individuals may have a larger volume of blood and body water, which can contribute to a lower blood alcohol concentration (BAC) compared to lighter individuals, assuming they consume the same amount of alcohol. This means that weight directly affects how alcohol is distributed throughout the body and how quickly it is absorbed into the bloodstream.

Other factors, such as the type of beverage and the presence of food in the stomach, also play important roles in absorption rates. However, weight is a fundamental physiological characteristic that consistently impacts how alcohol affects an individual's body and mind.
