C)                 Methyl acetate

D)                 Propionic acid

Correct Answer: A

Solution :

             \[\begin{matrix}    C{{H}_{3}}CO  \\    C{{H}_{3}}CO  \\ \end{matrix}\,>O\,+{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\] \[\underset{\text{Ethyl acetate}}{\mathop{2C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}}}\,\]
