Verified step by step guidance

1. Understand the role of hormones in the body's response to stress. Stress triggers a physiological reaction known as the 'fight or flight' response, which involves the release of specific hormones.
2. Identify the hormone options given: Oxytocin, Cortisol, Insulin, and Melatonin. Consider the primary functions of each hormone in the body.
3. Recall that Oxytocin is often called the 'love hormone' and is involved in social bonding and childbirth, not primarily stress response.
4. Recognize that Insulin regulates blood sugar levels and Melatonin regulates sleep-wake cycles, neither of which are directly increased due to stress.
5. Focus on Cortisol, which is known as the 'stress hormone' because its secretion from the adrenal glands increases during stress to help the body manage and adapt to stressors.
