Best answer
The correct option is (b) Surface charge

Easy explanation: Zeta potential is the measure of surface charge which is primarily determined by phosphate found in the cell wall mannoproteins and the pH of the surrounding medium. A curvilinear relationship is observed between increasing phosphate concentration and negative zeta potential.
