Step-by-step solution
Oogenesis is initiated during the embryonic development stage when oogonia form and enter prophase-I to become primary oocytes. Thus, (A) matches with (II). The primary oocyte completes its first meiotic division within the tertiary follicle prior to ovulation, forming a secondary oocyte and a first polar body. Thus, (B) matches with (IV). The Graafian follicle ruptures to release the secondary oocyte from the ovary during ovulation. Thus, (C) matches with (I). The second meiotic division is completed only when a s
