The correct option is
D All of the above
Oogenesis comprises three periods as multiplication, growth and maturation. During multiplication, the oogonia multiply by a series of mitosis. After mitosis oogonia enter into a growth phase and are called primary oocytes. Next phase is maturation which involves meiosis division and produces secondary oocyte and the first polar body. The second division gives rise to the second polar body and the mature ovum, which is haploid and capable of further development. Thus, the correct answer is option D.
