Solution

The correct option is B Corpus luteum
  • The corpus luteum is the structure that develops from the ruptured Graafian follicle.
  • It secretes progesterone that helps in maintaining the lining of the endometrium so that the uterus gets prepared for implantation.
  • This corpus luteum is yellowish in color.

So, the correct answer is 'Corpus luteum'
