According to selye, if your body's defenses are declining after dealing with a prolonged period of stress, you're at which stage of the gas?

The correct answer to this is:

“Exhaustion”

Selye states that if the stressor prolongs beyond the capacity of the body, we exhaust our own resources and becomes susceptible to disease and death. If the body’s resistance is weaker than the stress, then we reach the point of exhaustion.
