(D) In the process of frog oogenesis,the primary oocyte undergoes the first meiotic division (meiosis-$I$).During this division,the diploid $(2n)$ primary oocyte divides into two unequal haploid $(n)$ daughter cells: a large secondary oocyte and a small first polar body.Therefore,the reduction of the chromosome number from diploid to haploid occurs when the first polar body is separated.
