Which of the following compounds reacts with $NaOH$ to produce an acid and an alcohol?

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 $B$?

$PCl_5$ reacts with propanone to give:

An organic compound having the molecular formula $C_8H_{10}O$ on being heated with $I_2$ and dilute $NaOH$ gives a yellow precipitate. The expected compound is

Which statement is correct for product '$X$'?
$Cl-CO-CH_2-C(C \equiv CH)(CH_2-CN)-CH_2-CH_2-CO-CH_3 \xrightarrow{H_2/Pd/BaSO_4} X$

Organic products $A$ and $B$ are respectively -
