During prophase, the correct statement is:

**c) the nuclear envelope breaks down.**

Prophase is the first stage of mitosis, where the chromosomes condense and become visible, and the nuclear envelope begins to disintegrate, facilitating the separation of genetic material.

- Option a) occurs during the S phase of interphase, where DNA replication takes place before mitosis.
- Option b) refers to the movement of chromosomes, which primarily happens during metaphase and anaphase.
- Option d) refers to cytokinesis, which occurs after mitosis is complete.
