Solution:

Ans. Option a) is correct: Both statements 1 and 2 are correct. 

During the process of oogenesis in human females, the germ cells differentiated within the ovaries into oogonia these are diploid (2n) stem cells that divide mitotically to produce millions of germ cells, a few of these germ cells developed into large cells called primary oocytes surrounded by a single layer of follicular cells. The primary oocyte enter prophase I of meiosis I, during foetal development but do not complete that phase until after puberty. Whereas, further development of primary oocyte results the formation of first polar body after completion of division I of meiosis.

Graafian follicle is a mature follicle found in mammalian ovary. It is a matured form of tertiary follicle. It contains secondary oocyte surrounded by the zona pellucida. It bursts to release ovum into the fallopian tube by the induction caused by Luteinizing hormone (LH). After ovulation (release of ovum), it turns into corpus luteum.
