________ depress the central nervous system by interfering with the transmission of nerve impulses.

A) Narcotics
B) Sedatives
C) Cholinesterase inhibitors
D) Analgesics

Sedatives suppress the central nervous system by inhibiting the transmission of nerve impulses, leading to a calming or sleep-inducing effect. Narcotics and analgesics are pain-relieving medications, and cholinesterase inhibitors are used to treat conditions like Alzheimer's disease by increasing levels of neurotransmitters in the brain. None of these medications directly suppress the central nervous system in the way that sedatives do.
