Viscosity is defined as the measure of a fluid's resistance to flow. For example, honey has high viscosity because it resists flowing easily, while water has low viscosity as it flows freely. The other options are incorrect: option A describes fluidity, not viscosity; option C refers to material strength, an unrelated property.

Answer:

B. a substance's resistance to flow
