The correct option is B. Resistance.
Under a stressor, our body develops the general adaptation syndrome (GAS), which has three stages:
- Alarm: our body detects a stressor and activates the fight or flight response. Physiological changes happen during this stage. The heart rate increases, respiratory frequency increases, our pupils dilate, we consume a lot of energy since our muscles are tense, ready for action.
- Resistance: if the stressor is still present or our body feels there is still a threat, the physiological changes persist, and we can take action under this stress. In other words, we act on our decision to either fight or flight.
- Fatigue: in this stage, the stressor persists, but the body can not keep maintaining the physiological changes produced during the alarm stage. It demands energy that the body needs for other vital functions. As the stressor is still there and the body needs to deal with it, the body uses different resources. As a consequence of this stage, our immune system weakens, and chronic illnesses can appear. We can not resist the stress any longer.
In conclusion, we do no longer feel stressed and act during the resistance stage. The necessary physiological changes happened in the previous phase, and now we are ready to take action.
