What does "exhausted" mean?

The term "exhausted" refers to a state of being completely drained of energy, both physically and mentally. When someone is exhausted, they have reached a point where they feel a significant lack of strength or vitality, often as a result of strenuous activity, intense work, or prolonged stress. This word conveys a sense of total fatigue and an inability to continue functioning effectively due to depletion.

In contrast, the other choices describe states that are opposite to being exhausted, such as being rested, fully energized, or comfortable. These terms indicate a state of rest or vitality, which does not align with the meaning of "exhausted."
