Which of the following statements regarding body size and alcohol consumption is true?

The statement that someone who is smaller will get drunk faster is true due to the way body size affects blood alcohol concentration (BAC). Individuals with a smaller body size typically have a lower amount of body water compared to larger individuals. Since alcohol is distributed in body water, a smaller person has less water to dilute the alcohol consumed. As a result, even if both individuals consume the same amount of alcohol, the smaller person's BAC will rise more significantly, leading to faster intoxication levels.

This physiological principle underscores the importance of considering body size when evaluating the effects of alcohol. Similarly, it emphasizes that alcohol does not affect everyone equally and that body composition plays a crucial role in how alcohol is metabolized and its effects experienced.
