Solution

The correct option is C Prophase II
The first stage of meiosis divides the diploid set of chromosomes into two haploid sets. Homologous chromosomes separate in anaphase I, and at the beginning (prophase) of stage 2, each cell contains a haploid set. However, the chromosomes are still replicated and still consist of joined sister chromatids. These separate in anaphase II.
Thus, the correct answer is option C.
