Answer: (D)

Verified step by step guidance

1. Step 1: Understand the general effect of alcohol on the brain and motor skills. Alcohol is a central nervous system depressant that impairs cognitive functions, reaction time, coordination, and judgment, all of which are critical for safe motor vehicle operation.
2. Step 2: Recognize that tolerance to alcohol may reduce the subjective feeling of intoxication but does not eliminate the physiological impairments caused by alcohol consumption. This means even individuals with high tolerance experience impaired motor skills.
3. Step 3: Consider that experience in driving does not protect against the impairing effects of alcohol. While experienced drivers may have better baseline skills, alcohol still negatively affects their ability to operate a vehicle safely.
4. Step 4: Acknowledge that impairment occurs at various levels of alcohol consumption, not only at very high quantities. Even small amounts of alcohol can affect motor skills and reaction times.
5. Step 5: Conclude that alcohol impairs motor vehicle operation for all individuals regardless of tolerance or experience, making it unsafe to drive after consuming any amount of alcohol.
