Whereas the number of chromosomes is reduced to half in first reduction division of meiosis, then what is the need for second mitotic division?

Question

Whereas the number of chromosomes is reduced to half in first reduction division of meiosis, then what is the need for second mitotic division? (A) For the segregation of replicated chromosomes (B) For equal distribution of haploid chromosomes (C) For the formation of four gametes (D) For equal distribution of genes on chromosomes

In meiosis-I the actual chromosome number is reduced to half. Therefore, meiosis-I is also known as reductional division or heterotypic division. It results in the formation of two haploid cells from one diploid cell.
The second meiosis is required and it is ordinary mitosis because it is now turn of chromatids of the chromosome of haploid sets to segregate. Thus due to division, four haploid daughter cells (all may or may not be gametes) are finally formed.
