The correct option is C

i).➡ d., ii).➡ c., iii).➡ a., iv). ➡ b.,

Each endocrine gland has its specific site of action.

(i) GnRH or gonadotropin releasing hormone acts on gonads.

ii) ACTH or adrenocorticotrophic hormone acts on the adrenal gland (adrenal cortex) and stimulates the secretion of steroid hormones called glucocorticoids.

iii) TSH or thyroid stimulating hormone acts on the thyroid gland and stimulates the synthesis and secretion of thyroid hormones.

iv) Prolactin regulates the growth of mammary glands and the secretion of milk in them.
