The correct option is D Progesterone
In the luteal phase, there is the formation of corpus luteum under the influence of LH. Corpus luteum begins to secrete hormone progesterone and smaller amounts of estrogen and inhibin. Inhibin stops the further secretion of FSH. Under the influence of progesterone and LH, endometrium lining undergoes further thickening. Its glands become secretory. Uterine movements are reduced and the stage is set for receiving the fertilized ovum and its implantation.
