Which processing step marks the final permanence of the image?

Explanation:
The final permanence of the image occurs during fixing. Fixing dissolves and removes unexposed silver halide crystals from the emulsion, so only the developed image remains and it can no longer be affected by light. This makes the image stable and permanent. Developing creates the visible image, but it’s fixing that locks it in by removing the light-sensitive material that could continue to react. Rinsing and washing clean up chemicals and residues after fixing, but they don’t establish permanence themselves.
