During prophase, the correct answer is:
**B. The chromosomes are condensing (coiling up) and becoming visible.**
In this phase of mitosis, the chromatin condenses into distinct chromosomes, and each chromosome consists of two sister chromatids. The nuclear envelope begins to break down, but two nuclei are not forming yet, and the DNA duplication has already occurred in the previous phase (S phase). The actual cell division occurs later during cytokinesis.
