Creep can be described as a process of the slow rise of plastic deformation under the action of shear stresses when it is below the yield strength of the material. Hence, Option C is correct.
<h3>What do you mean by permanent deformation?</h3>
Permanent deformation can be defined as irreversible, the deformation remains even after the elimination of the carried out forces, at the same time as the transient deformation is recoverable because it disappears after the elimination of carried out forces.
therefore, the correct statement is Option C.

Answer:
c). surface pressure and depth
Explanation:
We know that fluid pressure is measured in two different ways namely --
1. Pressure measured above complete vacuum or absolute zero is called Absolute Pressure.
2.Pressure measured above atmospheric pressure is called Gauge Pressure.
In the figure below, we can find the pressure at the point A in the static fluid inside the tank which is at a depth of h from the water surface.
Let the atmospheric pressure which is acting on the water surface be .
Let ρ be the density of water and g be the acceleration due to gravity.
Therefore we know that pressure at a point in a fluid is
P = ρgh
Therefore total pressure acting on the point A in a fluid is
= + P
= + ρgh
Thus, pressure at a point A in a static fluid depends on the surface pressure and the depth of the point from the free surface.
