In sexual reproduction occurs Meiosis which has two stages I and II. The DNA content doubles but the number of chromosome remains same in S phase before the Meiosis I begins. So number will remain 50 before meiosis I. After meiosis I the number becomes 25. During Meiosis II the number till metaphase II will remain 25 as you know that during metaphase II, the chromosomes are lined up individually across the center of the cell. Due to the reduction division of meiosis I, there are now half as many chromosomes (and chromatids) as there were before. When anaphase II begins, however, the sister chromatids split apart, which once again doubles the chromosome number so anahase 2 the number will be 50.
so option is 1) 50
Please see the below pictures for examples to understand the number of chromosome at each stage.554-316_chromosome9.png
