Normal density of gold is p and its bulk modulus is K. Increase in density of a lump of gold when a pressure P is applied uniformly on all sides is:

• A

  $\frac{\mathrm{\rho P}}{\mathrm{K}}$

• B

  $\frac{P}{\mathrm{\rho K}}$

• C

  $\frac{\mathrm{K}}{\mathrm{\rho P}}$

• D

  $\frac{\mathrm{\rho K}}{\mathrm{P}}$
