The correct answer is A) The patient should be given sips of cool water salted with one teaspoon per glass at a rate of 1/2 glass every 15 minutes for one hour. This is the correct treatment because it provides the victim with a measured amount of cool, salted water to help replace fluids and electrolytes lost due to heat-related illness. Administering small, frequent sips of salted water is the recommended first aid approach, as it helps rehydrate the victim gradually without overwhelming the system. The other options, such as forcing large amounts of water or unsalted water, are not the optimal treatment for heat-related illness.
