Answer: (C)

Heavy sweating is a key symptom of excessive heat exposure associated with heat exhaustion. This condition occurs when the body becomes overwhelmed by heat and is unable to cool itself effectively. The body typically reacts to rising temperatures by increasing perspiration to dissipate heat through evaporation. In heat exhaustion, this sweating can be profuse, indicating that the body is attempting to regulate its temperature.

When sweating occurs excessively, it can lead to a loss of fluids and electrolytes, which can further aggravate feelings of nausea, weakness, and confusion. Recognizing heavy sweating as a symptom is crucial for identifying heat exhaustion and taking prompt action to cool the person down and restore hydration.

The other symptoms associated with heat exhaustion can include dizziness, nausea, and headache, but heavy sweating is distinctly characteristic as it represents the body's immediate response to combat heat stress.
