Density of a liquid at $0^{\circ }\mathrm{C}$ is 10.01 g/cc and at ${100}^{\circ }\mathrm{C}$ is  10g/cc.  Coefficient of real expansion of that liquid is 
 

• A

  $1\times {10}^{-5}{/}^0\mathrm{C}$

• B

  $1\times {10}^{-6}{/}^0\mathrm{C}$

• C

  $2\times {10}^{-5}{/}^0\mathrm{C}$

• D

  $3\times {10}^{-5}{/}^0\mathrm{C}$
