C

C and D only

D

D and E only

Step-by-Step Solution

Thyroid hormones play a crucial role in the regulation of basal metabolic rate (BMR), support the process of red blood cell (RBC) formation, and help in the maintenance of water and electrolyte balance. The sleep-wake cycle is primarily regulated by melatonin (secreted by the pineal gland), and the development of the immune system is not a primary function of thyroid hormones. Therefore, C and D are not under the control of thyroid hormones.
