Solution
The correct option is C Theca interna
The corpus luteum is a glandular body that forms from the remnants of the Graafian follicle after ovulation. It is the source of the hormones progesterone and estrogen during the second half of the ovulatory cycle. Theca interna cells express receptors for luteinizing hormone (LH) to produce estrogen. After rupture of the mature ovarian follicle, the theca interna cells differentiate into the theca lutein cells of the corpus luteum. Theca lutein cells secrete androgens and progesterone.
The theca externa is another layer of collagenous connective tissue.
The zona pellucida is a glycoprotein layer surrounding the plasma membrane of mammalian oocytes.
The corona radiata is the layers of cells which are directly adjacent to the zona pellucida.
