What factor influences how quickly a person feels the effects of alcohol, whether a man weighing 185 pounds or a woman weighing 110 pounds?

The correct answer is C. Gender and body weight affect how quickly a person feels the effects of alcohol. Gender plays a role because women generally have a higher percentage of body fat and lower percentage of water compared to men, leading to alcohol being less diluted in their bodies. Body weight is also a factor because alcohol can be more concentrated in a smaller body, such as a lighter person, leading to quicker intoxication. Time of day, alcohol concentration, and environmental temperature may influence other aspects of alcohol consumption but do not directly impact how quickly a person feels the effects of alcohol like gender and body weight do.
