Which of the following is most associated with stimulant effects rather than sedation?

Explanation:
Stimulants raise wakefulness and energy by boosting brain monoamines, especially dopamine and norepinephrine, which heightens alertness and focus. Amphetamines do this by increasing the release of these neurotransmitters and blocking their reuptake, leading to increased activity, motivation, and decreased appetite. The other substances tend to depress the central nervous system or cause drowsiness: opioids produce analgesia and sedation, alcohol is a CNS depressant, and antihistamines (especially older ones) often cause daytime sleepiness. So amphetamines are the one most associated with stimulant effects rather than sedation.
