Correct option is D
Shear modulus of rigidity:
The ratio of shearing stress to the corresponding shearing strain is called the shear modulus of the material and
It is represented by G.
It is also called the modulus of rigidity.
It is associated with the change in the shape of a body.
Note:
Young’s Modulus of Elasticity is related with the change in the length of a body.
The bulk Modulus of Elasticity is related with the change in the volume of a body.
