Explanation:
Answer is A because, production of gametes happens in meiosis. So, the first splitting of one cell into two daughter cell occurs in telophase I and then in each of these daughter cells in meiosis II those sister chromatids separate into full fledged chromosome and each daughter cell splits into two different cells. So at end you have 4 new non-identical daughter cells.
