A weight of 200 kg is suspended by vertical wire of length 600.5 cm. The area of cross-section of wire is  $1{\mathrm{mm}}^2$. When the load is removed, the wire contracts by 0.5 cm. The Young's modulus of the material of wire will be 

• A

  $2.35\times {10}^{12}N/m^2$

• B

  $1.35\times {10}^{10}N/m^2$

• C

  $13.5\times {10}^{11}N/m^2$

• D

  $23.5\times {10}^{9}N/m^2$
