• B. A- iii, B- iv, C- ii, D- i
• C. A-iv, B-i, C-iii, D-ii
  
• D. A-iii, B-i, C-iv, D-ii

Answer 1

The correct option is B A- iii, B- iv, C- ii, D- i

Prolactin, LH, and ACTH are hormones secreted by the anterior pituitary gland. Oxytocin is secreted by the posterior pituitary gland.

Prolactin regulates the growth of the mammary glands and formation of milk in them.

LH stimulates the synthesis and secretion of male sex hormones called androgens from testes in males, and induces ovulation and maintains the corpus luteum in females.

ACTH stimulates the synthesis and secretion of steroid hormones called glucocorticoids from the adrenal cortex.

Oxytocin stimulates a vigorous contraction of the uterus at the time of childbirth.
