Correct Answer: Adrenaline

Solution : The correct option is Adrenaline.

Adrenaline, commonly known as epinephrine, is a hormone. Adrenaline is known as the "Emergency Hormone" because it is essential in the body's "fight or flight" reaction to stressful or dangerous conditions. Adrenaline is released into the circulation when the body detects a threat, whether physical or psychological. Adrenaline elevates blood sugar, dilates airways, expands pupils, increases heart rate, redirects blood flow, and boosts strength to ready the body for swift action.
