AIIMS 2018 Botany Gametogenesis MCQ Question

Meiosis II in the ovum remains arrested in metaphase until fertilization occurs, which means it does not complete until a sperm cell penetrates the ovum. This process can happen many years after the initial meiotic division, typically during puberty when ovulation begins. Option (A) is incorrect because while the ovum is present at birth, it does not complete meiosis II until fertilization. Option (B) is misleading as it suggests that meiosis II is completed at puberty, but it is actually completed only upon fertilization.
