The prefix steno- is used to indicate which concept?

Explanation:
Steno- signals narrowing. This prefix comes from the Greek word for narrow, and it is used in medical terms to describe a constricted passage or channel. For example, stenosis refers to the narrowing of a vessel, valve, or canal. That’s why the concept tested is narrowing. It isn’t about opening (that would involve a root like stoma), growth (different roots such as -plasia or -phyte), or sound (phono-/son-).
