The correct answer is **D. only a phase change occurs.**
When water freezes, it changes from a liquid state to a solid state (ice), but its chemical composition (H2O) remains the same. This is why freezing is considered a physical change – it involves a change in state (phase change) without altering the molecular structure of the substance.
