Answer 2

Answer is option "b"

Explanation:

• The luteal phase or secretory phase usually includes days 15 - 28 in a 28 days cycle. It comes after ovulation. Ovulation involves the release of the matured ovum from the ovary. After ovulation, LH stimulates the development of the corpus luteum.  
• The corpus luteum then secretes increasing quantities of progesterone and the smaller amount of oestrogens. The progesterone prepares the endometrium for receiving the blastocyst and its implantation.
• Hence, the right answer is option b "Progesterone".
