Correct option is A
The correct answer is (a) Thyroid.
· The thyroid gland controls the rate of energy release inside the body by producing hormones like thyroxine (T4) and triiodothyronine (T3), which regulate metabolism.
· These hormones affect how the body uses energy and how quickly it burns calories.
Other Options:
· Parathyroid: Regulates calcium levels in the blood, not energy release.
· Pineal: Produces melatonin, which regulates sleep, not energy.
· Pancreas: Produces insulin and glucagon, regulating blood sugar but not directly controlling energy release.
