Answer #1

Option A.

The corpus luteum secretes progesterone thickening the endometrium of the uterus.

In females corpus luteum major role in maintaining pregnancy.Progesterone is a steroid hormone which is produced by corpus luteum which thickens the endometrium of the uterus.The thickening of the endometrium is done for the purpose of implantation of the fertilized egg.
