Solution

The correct option is B LH
Luteinising hormone (LH) secreted by the anterior lobe of pituitary gland stimulates corpus luteum of the ovary to secrete progesterone. The luteal phase is marked by the increased concentration of the luteinizing hormone. The LH stimulates the corpus luteum to secrete progesterone which helps in the maintenance of the pregnancy by increasing the thickening of the cell lining of the endometrial wall.
