The correct option is B Luteal phase and lasts for about 13 days

Secretory phase is the phase under corpus luteum, which last for 13 - 14 days in case of absence of pregnanacy. During the secretory phase of the uterus, the hormone progesterone is produced by the ovaries. Progesterone (as well as estrogen) is secreted by the corpus luteum, (which means yellow body), which develops from the Graafian follicle.
