Correct option is (b) False

For explanation I would say: Coefficient of viscosity is a constant of proportionality for the viscous force expression. Viscous force depends on the area of contact and the velocity gradient, and also on the temperature as more temperature of liquid will decrease friction between its layers hence we say that coefficient of viscosity depends on temperature.
