Explanation:

First Question (Drug Class Slowing CNS)

Stimulants speed up the CNS, hallucinogens alter perception, antidepressants treat mood disorders. Depressants (e.g., alcohol, benzodiazepines) slow CNS, causing drowsiness and slowed breathing.

Alcohol is a depressant, heroin is an opioid (depressant - like), LSD is a hallucinogen. Cocaine is a stimulant, increasing alertness and CNS activity.

Hallucinogens (e.g., LSD, psilocybin) primarily affect the serotonin neurotransmitter system, altering perception, mood, and cognition. Dopamine is linked to reward, GABA to inhibition, acetylcholine to muscle and memory.

Answer:

C. Depressants
