Explanation:

Tranquilizers are central nervous system depressants. Their pharmacological effects include slowing neural activity, leading to delayed reaction time, drowsiness, and impaired motor coordination—all critical impairments for driving. The other options describe stimulant or no relevant effects, which do not match tranquilizers' action.

Answer:

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