Answer:
The correct answer is B. Heat stroke
Step-by-step explanation:
Sweat glands secrete sweat which is 99% water. This sweat is released when the body temperature rises above normal. When sweat evaporates it causes cooling. Sweating is one of the methods by which we can maintain our body temperature.
Heatstroke is the most serious heat injury which occurs when our body temperature reaches above 40°c. If our sweat glands stop working at a very hot temperature than it will prevent cooling down of body temperature which can cause heatstroke. So the right answer is B.
