Find out the reactivity order of the labeled functional groups towards $LiAlH_4$ reduction.

Consider the following sequence of reactions.
$C_6H_5COONa$ $\xrightarrow[\Delta]{NaOH/CaO} X$ $\xrightarrow[\text{Anhy. } AlCl_3]{CO/HCl} Y$ $\xrightarrow[NaOH]{\text{conc. }} A + B$.
If $A$ is the reduction product of $Y$,what is $B$?

Methyl ketone group is identified by

$\alpha-H$ containing aldehyde and ketone reacts with dil $NaOH$ and gives $\beta-hydroxy$ aldehyde or $\beta-hydroxy$ ketone. This reaction is called $-$

Acetaldehyde cannot give:

What is the reduction of aldehydes and ketones in the presence of zinc amalgam and concentrated $HCl$ called?
