(a) Regulation of basal metabolic rate

(b) Erythropoiesis

(c) Maintenance of electrolyte balance

(d) Regulation of diurnal cycle

The question was asked during an online exam.

Answer 1

Right option is (d) Regulation of diurnal cycle

To explain I would say: Thyroid hormones are important for the regulation of basal metabolic rate. It also helps erythropoiesis and maintains water and electrolyte balance. However, the pineal gland regulates the diurnal cycle.
