Which one of the following gland is responsible for the secretion of growth hormones?

Pituitary Gland

The correct answer is Option (2) → Pituitary Gland

Pituitary Gland is responsible for the secretion of growth hormones.

The pituitary gland (often called the "master gland") located at the base of the brain, produces and secretes Growth Hormone (GH), also known as somatotropin, from its anterior lobe. GH regulates growth, cell reproduction, metabolism, and body composition, especially during childhood and adolescence.

• Pineal Gland: Secretes melatonin (regulates sleep-wake cycles).
• Thyroid Gland: Secretes thyroxine (T4) and triiodothyronine (T3) (regulates metabolism); also calcitonin.
• Adrenal Gland: Secretes cortisol, aldosterone, and adrenaline (stress response, electrolyte balance).
