I believe the answer is B (C). Mitosis is the process of cell division that takes place in the somatic cells where a parent cells divides in two diploid daughter cells. Prometaphase is the second phase of mitosis, the process separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During this stage, the physical barrier that enclose the nucleus (the nuclear envelop ) breaks.
