The symptoms of dizziness, confusion, and feeling faint in the heat suggest heat exhaustion, which is caused by the body being unable to regulate its temperature and eliminate excess body heat. This is especially common in older adults due to a decreased ability to sweat and cool down. It is important to move your grandfather to a cooler environment, hydrate him with cool water or sports drinks, and seek medical attention if his symptoms persist or worsen. The other options listed are less likely based on the given information.
