The effect that alcohol has on your reflexes and judgment:

The effect that alcohol has on your reflexes and judgment is primarily determined by the amount of alcohol present in your bloodstream. When you consume alcohol, it is absorbed into your bloodstream and has a direct impact on your central nervous system. As your blood alcohol concentration (BAC) increases, the more severe the impairment to your cognitive functions and physical reactions becomes. This means that even small amounts of alcohol can begin to affect reflexes and decision-making, with the effects becoming more pronounced at higher levels of consumption.

Other options suggest that the alcohol type (beer, wine, hard ciders, or mixed drinks) influences the extent of impairment, but the reality is that impairment correlates with the quantity of alcohol consumed rather than its specific type. Thus, option D correctly encapsulates the relationship between alcohol consumption and impairment based on blood alcohol levels.
