An individual weighing 120 pounds consumed one standard alcoholic beverage 30 minutes ago. Which statement best explains why driving right away would be unwise?

One standard drink can raise blood alcohol concentration to levels known to impair coordination and reaction time within 30 minutes.

One standard drink will always result in a BAC under 0.02% for people under 140 lb, so any impairment is negligible.

 Alcohol must be present for at least 2 hours before it causes any measurable impairment, so 30 minutes is too soon to worry.

Eating food after the drink makes BAC zero immediately, so driving is safe after eating.
