    A)  \[NaHC{{O}_{3}}\]   

    B)  \[NaHS{{O}_{4}}\]

    C)  \[Cone.\text{ }HCl\]

    D)  None of these

    Correct Answer: A

    Solution :

    Carboxylic acids evolve \[C{{O}_{2}}\]with brisk effervescence with \[NaHC{{O}_{3}}\]solution. While carbonyl compounds do not react with it. \[R-COOH+NaHC{{O}_{3}}\to R-COONa\]                                                 \[+{{H}_{2}}O+C{{O}_{2}}\uparrow \]
