The given product cannot be obtained in the above reaction. Identify the correct product obtained.

When $32.25 \ g$ of ethyl chloride undergoes dehydrohalogenation,it yields $50\%$ of the theoretical alkene product. What is the mass of the product obtained in $g$? (Atomic mass: $Cl = 35.5, C = 12, H = 1$)

The reactions which cannot be applied to prepare an alkene by elimination are: Choose the correct answer from the options given below $:$
$A.$ $2$-bromomethylcyclohexane + $NaOEt$
$B.$ $2$-bromobutane + $KOH$ (aq.)
$C.$ $2$-bromo-$2$-methylpropane + $NaOMe$
$D.$ Phenol + $Na_2Cr_2O_7 / H_2SO_4$
$E.$ $2$-methylpropan-$2$-ol + $Cu$ at $573 \ K$

Assertion : Alkylbenzene is not prepared by Friedel-Crafts alkylation of benzene.
Reason : Alkyl halides are less reactive than acyl halides.
