To determine the stage of meiosis represented in the picture, we can analyze the characteristics of the model. In meiosis, chromosomes condense and align in the middle of the cell during metaphase I and metaphase II.
In the given picture, individual chromatids are moving towards opposite poles, which indicates that they have already separated. This means that the depicted stage is after the separation of homologous chromosomes during anaphase I or anaphase II.
Since the question specifies that it is a phase of meiosis, we can rule out anaphase II since it is a phase of mitosis, not meiosis. Therefore, the correct answer is:
A) anaphase II
