Which of the following statement is wrong?

[A].	The deformation of the bar per unit length in the direction of the force is called linear strain.	[B].	The Poisson's ratio is the ratio of lateral strain to the linear strain.
[C].	The ratio of change in volume to the original volume is called volumetric strain.	[D].	The bulk modulus is the ratio of linear stress to the linear strain.

Answer: Option D
