DNA-copying errors most likely occur during the **A. S phase** of the cell cycle. The S phase (Synthesis phase) is when DNA replication occurs, and that's when the DNA is copied to prepare for cell division. Errors during this replication process can lead to mutations and potentially contribute to cancer development.
