If x is a hormone which controls the carbohydrate metabolism in the body and Y is a hormone which controls the secretion of X, then X and Y are?

The correct option is C Glucocorticoid and ACTH, respectively
Adrenocorticotropic hormone (ACTH) is a 39 amino acid peptide hormone produced by cells of the anterior pituitary gland and carried by the peripheral circulation to its effector organ, the adrenal cortex, where it stimulates the synthesis and secretion of glucocorticoids.

A glucocorticoid is a hormone that affects the metabolism of fats and proteins, but especially carbohydrates.

So, the correct option is 'Glucocorticoid and ACTH, respectively'.
