Which of the following is not listed as a method to control suspensions in pharmaceutics?

Explanation:
Controlling suspensions focuses on factors that change how fast particles settle and how easily the suspension can be redispersed. You actively adjust particle size (smaller radius slows settling), the viscosity of the medium (a more viscous vehicle reduces sedimentation), and the stirring rate (affects uniformity during use and redispersement). Color, while important for appearance, does not influence the physics of settling or stability, so it isn’t a method used to control suspension behavior.
