The correct answer is: $\mathrm{CH}_3 \mathrm{CHO}$
The aldehyde/ketone, those do not contain $\alpha$-H atom; show Cannizzaro reaction.
In $\mathrm{CH}_3 \mathrm{CHO}$, carbonyl group is attached to C-atom having $\alpha-\mathrm{H}$; Hence, $\mathrm{CH}_3 \mathrm{CHO}$ do not show Cannizzaro reaction.
