The freezing point of water is depressed by ${0.37\mathrm{}}^{\mathrm{o}}\mathrm{C}$ in a 0.01 molal $\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}$ solution. The freezing point of 0.02 molal solution of urea is depressed by

• Correct answer
  A

  ${0.37\mathrm{}}^{\mathrm{o}}\mathrm{C}\mathrm{}$
• B

  $0{\mathrm{}}^{\mathrm{o}}\mathrm{C}$
• C

  $0.56{\mathrm{}}^{\mathrm{o}}\mathrm{C}$
• D

  $0.187{\mathrm{}}^{\mathrm{o}}\mathrm{C}$

Hence, the correct answer is option: 'A'.
