Which prefix denotes sleep?

Explanation:
The concept being tested is recognizing a prefix that indicates sleep. The best answer is narc- (also seen as narco-). This prefix comes from a root meaning numbness or sleep, and it appears in medical terms like narcolepsy, where it refers to sudden sleep attacks, and narcosis or narcotic, which describe sleep-like stupor or substances that induce sleep. The other prefixes point to something different: nas(o) relates to the nose, necr(o) to death, and neo- to something new. So narc- is the one that signifies sleep.
