Which of the following is a category of CNS stimulants?

Explanation:
CNS stimulants raise activity in the brain, boosting wakefulness, attention, and energy. Among the options, amphetamines fit this category because they increase dopamine and norepinephrine in the central nervous system by promoting release and blocking reuptake, which drives the heightened alertness and focus characteristic of stimulant drugs. Antihistamines are mainly sedating, not stimulants; benzodiazepines depress CNS activity by enhancing GABA signaling; and opioids act on opioid receptors to depress CNS function and relieve pain. So the stimulant category is represented by amphetamines.
