Which of the following is not a function of glucocorticoid?

The correct option is D Stimulates reabsorption of water
Cortisol is the main glucocorticoid synthesised by adrenal cortex (outer region) of the adrenal gland. It stimulates gluconeogenesis, lipolysis and proteolysis and inhibit cellular uptake and utilisation of amino acids. It also produces anti-inflammatory reactions and suppresses the immune response. They also stimulate RBC production.

Aldosterone is a mineralocorticoid acts mainly at the renal tubules and stimulates the reabsorption of Na+ and water and excretion of K+ and phosphate ions. Thus, aldosterone helps in the maintenance of electrolytes, body fluid volume, osmotic pressure and blood pressure.
