<span>The answer is B. four haploid cells. In the meiosis, the number of chromosomes is reduced by half. It consists of meiosis I and II. In meiosis I, 2 haploid cells are formed from a diploid mother cell. These 2 haploid cells undergo meiosis II which is similar to mitosis. As the result of meiosis II, 2 haploid cells form from each haploid mother cell. Therefore, as the result of meiosis, 4 haploid cells are formed.</span>
