Solution

The correct option is A
viscosity

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluid having low viscosity flows easily as the resistance within the layers is comparitively less i.e. there is very little friction between the layers when it is in motion.
