Which of the following is NOT a factor affecting clearing time?

Explanation:
Clearing time is about how quickly the fixer dissolves and removes unexposed silver halide from the film emulsion during fixation. This is influenced by how much material needs clearing (thicker emulsions take longer), the fixer’s strength and freshness (a properly concentrated, active fixer clears faster; exhaustion slows it), and processing conditions that affect chemical action. Washing duration, by contrast, is simply rinsing away residual chemicals after fixation and does not alter the chemical rate of clearing. So washing duration does not affect clearing time.
