What strategy for avoiding heat exhaustion is most likely to result in more severe pain as associated with heat cramps?

Correct Answer: Option B — Drinking excessive water lost during profuse sweating without replacing the salt lost.

Heat cramps occur when excessive water is consumed without replacing lost electrolytes, specifically salt. This dilution of body fluids disrupts muscle function. To prevent this, personnel working in hot engine spaces must replace both water and salt lost through sweating to maintain proper physiological balance and avoid severe cramping.
