Solution

The correct option is D Generative epithelium
Germinal epithelial cells (diploid) undergo mitosis (multiplication) before birth, forming many oogonia. The oogonia undergo significant growth, forming primary oocytes protected in the primary follicle. Primary oocytes undergo meiosis I, forming a large secondary oocyte plus a small polar body with little cytoplasm, both protected inside a Graafian follicle.
Therefore, the correct answer is option B.
