Step-by-step solution
A. Oogonia formation: Oogenesis is initiated during the embryonic development stage when a couple of million oogonia are formed within each fetal ovary. (A matches with 2) B. Primary oocyte arrest: The oogonia start division and enter into prophase-I of the meiotic division and get temporarily arrested at that stage, called primary oocytes. (B matches with 1) C. First polar body formation: The primary oocyte within the tertiary follicle grows in size and completes its first meiotic division prior to ovulation (at p
