The correct answer is resistance stage.
Hans Selye was a very important endocrinologist working in the field of biological stress. He developed the General Adaptation Syndrome (GAS) which is a model describing an animal's response to stress. GAS is comprised of three stages; the alarm, the resistance and the exhaustion stage.
