Narcotics are drugs that relieve pain and produce sleep. Which of the following best fits this category?

Explanation:
Narcotics are opioid analgesics that relieve pain and often cause sedation. Morphine is the classic example of this category, working by binding to mu-opioid receptors to block pain signals and commonly producing drowsiness. The other drugs are not narcotics: amphetamine is a stimulant that increases alertness and energy; cocaine is a stimulant with strong cardiovascular effects; LSD is a hallucinogen that alters perception. So morphine best fits the description of narcotics.
