Which of the following is a depressant that slows neural activity and body functions?

Explanation:
Depressants slow brain activity and bodily functions. Alcohol does this by enhancing the brain’s inhibitory signals (GABA) and dampening excitatory signals (glutamate), which lowers neuron firing rates. That causes slower thinking, slowed reflexes, impaired coordination, and, at higher doses, slower breathing. Caffeine is a stimulant that increases neural activity, and LSD is a hallucinogen that primarily alters perception rather than slowing brain activity. Heroin is also a depressant that slows bodily functions, but alcohol is the classic, widely recognized example used to illustrate the slowing of neural activity in everyday contexts.
