47) The property of fluid by virtue of which it offers resistance to shear is called

surface tension

adhesion

cohesion

viscosity

Answer is:

viscosity

Explanation:

Viscosity is also known as absolute viscosity or dynamic viscosity. It is defined as the property of a liquid which offers resistance to the movement of one layer of liquid over another adjacent layer of liquid. The viscosity of a liquid is due to cohesion and interaction between particles.
