Solution

The correct option is B LH
LH is the hormone that is not secreted by human placenta. It is secreted by anterior pituitary. Initially during pregnancy, hCG performs the function of LH of maintaining corpus luteum for the secretion of progesterone. Later (around 16th week) in pregnancy, when placenta itself starts secreting estrogen and progesterone, corpus luteum regresses.
