Statement given in option (e) is true but rest are false. The reciprocal of the bulk modulus (B) of a body is called the compressibility (C) of that material, i.e. C=
1
B
However, Young's modulus (Y) of a wire is independent of its length. Unit of Y is Nm−2. Dimensional formula of stress is same as that of pressure. Strain is a unitless and it is dimensionless physical quantity.
