An external pressure P is applied on a cube at `0^(@)C` so that it is equally compressed from all sides. K is the bulk modulus of the material of the cube and `alpha` is its coefficient of linear expansion. Suppose we want to bring the cube to its original size by heating. The temperature should be raised by

A

`3PK alpha`

B

`(P)/(3 alpha K)`

C

`(P)/(alpha K)`

D

`(3 alpha)/(PK)`
