Which among the following is $NOT$ obtained when bromobenzene is treated with bromoethane and sodium in the presence of dry ether?

Match the reactants in Column-$I$ with the products in Column-$II$.

Column-$I$ (Reactants)	Column-$II$ (Products)
$(A) CH_3CH_2Br + Mg \xrightarrow{\text{dry ether}}$	$(i) \text{Cyclohexylmagnesium bromide}$
$(B) 2RX + 2Na \xrightarrow{\text{dry ether}}$	$(ii) CH_3CH_2MgBr$
$(C) CH_3CH_2Br \xrightarrow{\text{alc. KOH}}$	$(iii) R-R + 2NaX$
$(D) \text{Bromocyclohexane} + Mg \xrightarrow{\text{dry ether}}$	$(iv) CH_2=CH_2 + H_2O + KBr$

In the following reaction sequence, $X$ and $Z$, respectively, are:
$CH_{3}CH_{2}CH_{2}-OH + PCl_{5} \rightarrow CH_{3}CH_{2}CH_{2}Cl + X + HCl$
$CH_{3}CH_{2}CH_{2}Cl \xrightarrow{alc. KOH, \Delta} Y$
$Y \xrightarrow{HBr, (C_{6}H_{5}CO)_{2}O_{2}} Z$

Product $A$ is
