Which word describes a period of relief or rest?

The word that describes a period of relief or rest is "respite." This term specifically refers to a temporary pause or interval of relief from something difficult or challenging. It suggests a break that allows for recovery or a moment free from stress. For example, after a long day of work, someone might seek respite through a relaxing evening at home.

In contrast, the other options imply different meanings. "Exhaustion" refers to a state of extreme physical or mental fatigue, which indicates a lack of relief. "Panic" describes a sudden overwhelming fear or anxiety, which is contrary to the concept of rest. "Urgency" denotes a state of needing immediate attention or action, which does not align with the idea of taking a break or finding relief.
