B is correct: Reduced urine output shows significant fluid loss, and confusion shows the nervous system is affected, indicating severe dehydration or heat illness.

Other Options:

A is incorrect: Cramping with normal sweating can be managed by stopping and rehydrating, and is not yet an emergency.
C is incorrect: Rapid breathing and thirst are expected responses to hard exercise in heat.
D is incorrect: Fatigue and hunger are expected after prolonged exercise.
