Which word refers to something that has been halted momentarily?

The term that describes something that has been halted momentarily is "pause." When you pause something, it implies a temporary cessation of activity with the intention of resuming it later. This is distinct from the other choices, which convey different meanings: "interrupted" refers to an abrupt disruption that may not be intended to resume smoothly; "delayed" suggests that something is postponed for a period longer than a mere moment; and "stopped" indicates a complete cessation without implication of resumption. Therefore, "pause" specifically captures the essence of a temporary halt, which aligns best with the given context.
