Option 1 -> Pineal Gland secretes melatonin, which regulates sleep-wake cycles.
Option 2 -> Pituitary Gland, specifically the anterior pituitary, produces and secretes growth hormone (GH).
Option 3 -> Thyroid Gland produces thyroid hormones (T3 and T4) that regulate metabolism.
Option 4 -> Adrenal Gland produces hormones like cortisol and adrenaline for stress response.
Hence, Option 2: Pituitary Gland -> The anterior pituitary gland is the master gland that produces growth hormone (somatotropin), which is essential for growth, cell reproduction, and regeneration throughout the body, particularly during childhood and adolescence -> correct
