Final answer:
A driver with a BAC of .10% is 25 times more likely to cause a crash than a sober driver. So, the correct answer is option d
Step-by-step explanation:
If a driver reaches a BAC of .10% after drinking alcohol, their chance of causing a crash is 25 times greater compared to someone who hasn't consumed any alcohol. This higher BAC increases the risk significantly due to the impact that alcohol has on a driver's reaction time, judgment, and overall ability to operate a vehicle safely.
As alcohol consumption increases, so does the level of impairment and the associated risk of being involved in a motor vehicle accident. So, the correct answer is option d.
