Correct option (d) Separation of chromatids
Explanation :
Meiosis-II is homotypic or equational division similar to mitosis but occurs in haploid nuclei Meiosis-II is essential to separate out the chromatids of diad chromosomes to bring real haploidy in amount of DNA. It also increases the number of daughter cells though the chromosome number remains the same in daughter cells as produced after meiosis-I.
