During prophase, the correct statement is **d**: "the nuclear envelope breaks down."
Prophase is the first stage of mitosis where the chromatin condenses into visible chromosomes, the spindle apparatus begins to form, and the nuclear envelope starts to disintegrate. The chromosomes do not begin to move until later stages (such as metaphase and anaphase), and the cell does not separate into two new cells until the later stage of cytokinesis. Also, genetic material duplication occurs during the S phase of interphase, prior to mitosis.
