Vedclass · Answer

(B) The reaction shows the hydrolysis of a cyclic acetal (specifically,a $1,3-$dioxolane derivative) to regenerate the original aldehyde (benzaldehyde) and the diol (ethylene glycol).Acetals are stable in basic conditions but undergo hydrolysis to aldehydes or ketones in the presence of aqueous acid.Therefore,the correct condition is $H_2O, H_2SO_4, 	ext{heat}$ (acidic hydrolysis).Thus,the correct option is $(B)$.
