19yes both will react and reduce BOTH the double bond and aldehyde group
(1) lithium aluminium hydride is known to reduce all groups....hence not much of thinking !!
(2) sodium borohydride generally reduces only aldehyde group to alcohol.....but due to high mobility of the double bond in the cinnamyl system, this weak reducing agent will also reduce the double bond here along with the aldehyde group as usual !!!
119lithium aluminium hydride has no special reason of reduction here.....it reduces all groups....very strong reducing agent !
