    C)  dihydroxy acetone

    D)  tartronic acid        

    Correct Answer: A

    Solution :

                    Glycerol on oxidation with bismuth nitrate gives mesooxalic acid. \[\underset{glycerol}{\mathop{\underset{\begin{smallmatrix}  | \\  C{{H}_{2}}OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{2}}OH \\  | \end{smallmatrix}}{\mathop{CHOH}}}\,}}\,\xrightarrow[{}]{Bi{{(N{{O}_{3}})}_{2}}}\underset{mesooxalic\text{ }acid}{\mathop{HOOC-\overset{\begin{smallmatrix}  O \\  |\,| \end{smallmatrix}}{\mathop{C}}\,-COOH}}\,\]
