Reagent(s) which can be used to bring about the following...

$LiAl{H}_{4}$ in ${\left({C}_{2}{H}_{5}\right)}_{2}O$, $B{H}_{3}$ in ($THF$), Raney  $Ni / {H}_{2}$ either can reduce all functional groups or can reduce some of the functional groups of the compound given above in the reactant side. But, $NaB{H}_{4}$ is an example of selective reducing agent. It cannot reduce, (ester group) , (carboxylic acid group) , (epoxide group). But reduces $- CH = O$ (aldehyde group) into $- C{H}_{2}OH\left({1}^{o}alcohol\right)$.
