Which alkyl halide has the highest bond enthalpy of the $C-X$ bond?

Which of the following would not give $2-$phenylbutane as the major product in a Friedel-Crafts alkylation reaction?

The major product of the following reaction is:

Assertion $A:$ Hydrolysis of an alkyl chloride is a slow reaction but in the presence of $NaI$,the rate of the hydrolysis increases.
Reason $R:$ $I^{-}$ is a good nucleophile as well as a good leaving group.
In the light of the above statements,choose the correct answer from the options given below.

Match the following:

Reactants	Products
$A$. $C_2H_5Cl$,moist $Ag_2O$	$I$. $CH_3CH_2ONO$
$B$. $C_2H_5Cl$,aqueous ethanolic $AgCN$	$II$. $C_2H_4$
$C$. $C_2H_5Cl$,aqueous ethanolic $AgNO_2$	$III$. $CH_3CH_2OH$
$D$. $C_2H_5Cl$,ethanolic $KOH$	$IV$. $CH_3CH_2NC$

The correct match is:

$1$-chlorobutane on reaction with alcoholic potash gives
