After an alarming event, your temperature, blood pressure, and respiration are high, and you have an outpouring of hormones. han
Marrrta [24]

Answer: The correct answer for the question is- Resistance phase.

"General Adaptation Syndrome" is a model of stress, which was proposed by  Hans Selye in 1936.

This model explains stress response ( through three phases that is Alarm phase, resistance phase, and exhaustion phase) and how it is related to aging and disease of organisms on exposure to stressful situations.

According to Resistance phase ( that is a second phase of stress response) of this model, the level of stress is declined once a body gives response to the stress. After the first phase ( alarming phase), overall temperature, blood pressure, and respiration becomes high.

As the stressor situation persist, the body is required to fight against the situation continuously, which is accompanied by outpouring of hormones.
