A ball falling in a lake of depth 200 m shows a decrease of 0.1% in its volume at the bottom. The bulk modulus of the elasticity of the material of the ball is $\left(\text{ take }\mathrm{g}=10{\mathrm{ms}}^{-12}\right)$

• A

  ${10}^9\mathrm{N}/{\mathrm{m}}^2$

• B

  $2\times {10}^9\mathrm{N}/{\mathrm{m}}^2$

• C

  $3\times {10}^9\mathrm{N}/{\mathrm{m}}^2$

• D

  $4\times {10}^9\mathrm{N}/{\mathrm{m}}^2$
