According to the GAS (General Adaptation System), the stage one will experience the activation of the adrenal pituitary cortex system for fight or flight?

Alarm Reaction Stage

The correct answer is Option (3) → Alarm Reaction Stage

According to the General Adaptation Syndrome (GAS) model proposed by Hans Selye, the Alarm Reaction Stage is the first stage of the stress response, during which:

• The adrenal-pituitary-cortex system is activated.

• The body prepares for fight or flight by releasing stress hormones (like adrenaline and cortisol).

Other stages:

• Resistance Stage: The body tries to adapt and cope with the stressor.

• Exhaustion Stage: The body's resources are depleted after prolonged stress.

• Burnout: Not a formal stage of GAS, but a result of chronic stress.
