Answer : The correct option is, surface tension.
Explanation :
Viscosity : It is defined as the resistance of a liquid to flowing.
Condensation : It is a physical process in which a phase of matter converted from gas phase to liquid phase.
Evaporation : It is a process in which a phases changes from liquid phase to gas phase.
Surface tension : It is defined as a force present within the layer of a liquid that causes the layer act as an elastic sheet.
Therefore, the surface of water can act like a sort of skin due to a property of liquids called surface tension.
