Final answer:
A young, lean man is likely to have the lowest Blood Alcohol Concentration (BAC) after consuming the same amount of alcohol due to higher water content in the body and faster metabolism compared to older men and women.
Step-by-step explanation:
The question asks which of the following customers will likely have the lowest Blood Alcohol Concentration (BAC) after consuming the same number of standard drinks in the same amount of time. Given that metabolic rates vary and women generally metabolize alcohol more slowly than men, a young, lean man (Option 1) will likely have the lowest BAC out of the options provided.
Men typically have a higher percentage of water in their bodies than women, which means alcohol becomes more diluted in their systems leading to a lower BAC. Moreover, younger individuals often metabolize alcohol faster than older individuals. These factors contribute to the lower BAC in young, lean men compared to the other options listed.
