Explanation:

Tranquilizers are central nervous system depressants. They reduce neural activity, leading to slower reaction times, drowsiness, and impaired motor coordination—all critical for safe driving. The other options are incorrect because tranquilizers do not enhance perception or reflexes.

They slow reaction time and cause drowsiness and lack of coordination.
