Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
The endocrine system releases hormones to help the body react quickly to stress or perceived danger.
Step 2: Meaning
The "fight or flight" response is a physiological reaction that increases heart rate, blood pressure, and energy supplies.
Step 3: Analysis
Insulin regulates blood sugar, thyroxine controls metabolism, and estrogen is a sex hormone. Adrenaline (epinephrine), secreted by the adrenal glands, triggers the immediate physical changes needed to either confront or flee from a threat.
Step 4: Conclusion
Adrenaline is the primary hormone that prepares the body for sudden physical exertion during emergencies. Final Answer: (C)
