Pressure of a medium is changed from $1.01 \mathrm{x} {10}^5\mathrm{N}/{\mathrm{m}}^2 \mathrm{to} 1.11 \mathrm{x} {10}^5 \mathrm{N}/{\mathrm{m}}^2$ and change in volume is 5% keeping temperature constant. The bulk modulus of the medium is, 

• A

  204.8 x 10⁵ pa

• B

  2 x 10⁵ pa

• C

  2.45 x 10⁵ pa

• D

  3.05 x 10⁵ pa
