The correct answer is:

b the nuclear envelope breaks down and chromatin condenses into chromosomes.

During prophase, which is the first stage of mitosis, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. The other options describe processes that occur at different stages of the cell cycle.
