The property of fluid by virtue of which it offers resistance to shear...
Viscosity is a property of a fluid by virtue of which it offers resistance to flow. The shear stress at a point in a moving fluid is directly proportional to the rate of shear strain. ... The relationship is known as the Newton's law of viscosity and the fluids which obey this law are known as Newtonian fluids.

The property of fluid by virtue of which it offers resistance to shear...
The correct answer is option 'D' - viscosity.
Viscosity is the property of a fluid by virtue of which it offers resistance to shear or flow. It is a measure of the internal friction within a fluid or the resistance to flow. This property arises due to the cohesive forces between the molecules of a fluid.
Viscosity is caused by the interaction between the molecules of a fluid as they move past one another. The molecules in a fluid are constantly in motion and they interact with each other through intermolecular forces. These forces create resistance to the flow of the fluid, resulting in viscosity.
Viscosity can be thought of as the thickness or stickiness of a fluid. High viscosity fluids are thick and flow slowly, while low viscosity fluids are thin and flow easily. For example, honey has a high viscosity, while water has a low viscosity.
Viscosity is an important property in various applications, especially in fluid mechanics and engineering. It affects the flow behavior of fluids in pipes, channels, and other systems. Viscosity also plays a role in the performance of lubricants, paints, and coatings.
The SI unit of viscosity is pascal-second (Pa·s) or N·s/m². Common units used to express viscosity include poise (P) and centipoise (cP).
In conclusion, viscosity is the property of a fluid that offers resistance to shear or flow. It is caused by the cohesive forces between the molecules of the fluid and affects the flow behavior of fluids in various applications.
