Solution
The correct option is B 36 single-stranded chromosomes Mitosis is an equational division, that forms two cells at the end of the division, that has same number of chromosomes as that of the parent cell. During Anaphase of Mitosis each chromosome splits into two along its centromere, and sister chromatids (equivalent to chromosome, but single strand) are pulled towards opposite poles given rise to two cells with same number of chromosomes.
So, the correct answer is ' 36 single-stranded chromosomes'
