The answer is C. When a cell is undergoing mitosis or meiosis, after interphase, the single --stranded chromsomes have been duplicated forming pairs of chromatids. They are held together by a centromere. By duplicating the chromosome material, this will insure that the proper amount of chromosomes will end up in the daughter cells after mitosis, or in the gametes, after meiosis.
