Match List I with List II
List I (Hormone) List II (Activity)
a. Melatonin i. Muscle growth
b. Epinephrine and Norepinephrine ii. Hyperglycemia
c. Glucagon iii. Fight or flight
d. Androgen iv. Sleep wake cycle
Choose the correct answer from the options given below:

Correct option is C

The Correct answer is(c) a-iv, b-iii, c-ii, d-i
Explanation:
 Melatonin (a) is secreted by the pineal gland and regulates the 24-hour  sleep-wake cycle (circadian rhythm). Thus, a-iv.
 Epinephrine and Norepinephrine (b) are released by the adrenal medulla in response to stress and are called "fight or flight" hormones. Thus, b-iii.
 Glucagon (c) is a hormone produced by the pancreas that raises blood glucose levels (causing  hyperglycemia) by stimulating glycogenolysis and gluconeogenesis in the liver. Thus, c-ii.
 Androgens (d), such as testosterone, are steroid hormones that promote the development of male characteristics and have an anabolic effect on skeletal muscles, leading to increased  muscle growth and strength. Thus, d-i. 
Information Booster:
 Melatonin is often called the "hormone of darkness" because its production increases in the evening and drops in the morning in response to light.
 Epinephrine and norepinephrine also increase heart rate, blood pressure, and alertness during an emergency.
 Glucagon works antagonistically with insulin to maintain blood sugar homeostasis.
 Androgens act by binding to androgen receptors found in various tissues, including muscle cells.
