Ethanol on reaction with acetic anhydride gives

The acid strength of the active methylene group in
$(a)$ $CH_3COCH_2COOC_2H_5$
$(b)$ $CH_3COCH_2COCH_3$
$(c)$ $C_2H_5OOCCH_2COOC_2H_5$
decreases as:

The major products $A$ and $B$ in the following set of reactions are:

Identify the correct option based on the following reaction sequence:
Acetic anhydride $\xrightarrow[(ii) EtOH/H^+/\Delta]{(i) H_3O^+} (A)$ $\xrightarrow[(ii) H_3O^+/\Delta]{(i) NaOEt} (B)$

$A$ $\xrightarrow[\text{(ii) } H_3O^{+}]{\text{(i) } NaOH} B$ $\xrightarrow[\text{(ii) } H_2SO_4, \Delta]{\text{(i) } EtOH} C$
'$A$' shows positive Lassaigne's test for $N$ and its molar mass is $121$.
'$B$' gives effervescence with aq. $NaHCO_3$.
'$C$' gives fruity smell.
Identify $A, B$ and $C$ from the following.

Match the reactions given in Column-$I$ with their products in Column-$II$.

Column-$I$ (Reactant)	Column-$II$ (Product)
$A$. $RCH_2OH \xrightarrow[(ii) H_3O^{+}]{(i) NaOH, KMnO_4} ?$	$i$. $C_6H_5COOH + C_2H_5OH$
$B$. $CH_3(CH_2)_8CH_2OH \xrightarrow{Jones reagent} ?$	$ii$. $RCOOH$
$C$. $RCONH_2 \xrightarrow{H_3O^{+}, \Delta} ?$	$iii$. $CH_3(CH_2)_8COOH$
$D$. $C_6H_5COOEt \xrightarrow{H_3O^{+}} ?$	$iv$. $RCOOH + NH_3$
