Answer:
e. a replicate chromosome
Explanation:
In the cell that is in the process of division, each condensed chromosome appears as a pair of rods joined at one point, the centromere. These two chromosomal "halves", called sister chromatids, are identical and arise from the duplication of the original chromosomal filament that occurs at the interphase just before cell division begins.
During the process of cell division, the sister chromatids separate: each chromatid migrates to one of the forming daughter cells.
