# Which of the following is an example of aldol condensation?

$\begin{array}{1 1} a \\ b \\ c \\ d \end{array}$

HCHO and Benzaldehyde lack alpha hydrogen , so they can not undergo aldol condensation, instead they can undergo canizzaro reaction. But $CH_3COCH_3$ has alpha hydrogen so in presence of aqueous base it undergoes aldol condensation.
