The oxygen atom in an ether is:

What is $X$ in the following reaction?
$C_2H_5OC_2H_5 + 4[H] \xrightarrow{Red \ P + HI} 2X + H_2O$

Ethers are prepared from alcohols by Williamson synthesis. Heating ethanol with sulfuric acid at $413 \ K$ gives ethoxyethane. Match the ether compounds in Column-$I$ with the products formed upon heating with $HI$ in Column-$II$.

Column-$I$ (Ether)	Column-$II$ (Product)
$(A)$ $CH_3CH_2-CH(CH_3)-CH_2-OCH_2CH_3$	$(i)$ $CH_3OH + CH_3-C(CH_3)_2-I$
$(B)$ $CH_3CH_2CH_2-O-C(CH_3)_2CH_2CH_3$	(ii) $C_6H_5OH + C_6H_5CH_2I$
$(C)$ $C_6H_5CH_2-O-C_6H_5$	(iii) $CH_3CH_2CH_2OH + CH_3CH_2-C(CH_3)_2-I$
$(D)$ $CH_3-C(CH_3)_2-O-CH_3$	(iv) $CH_3CH_2-CH(CH_3)-CH_2OH + CH_3CH_2I$

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R).$
Assertion $(A):$ Synthesis of ethyl phenyl ether may be achieved by Williamson synthesis.
Reason $(R):$ Reaction of bromobenzene with sodium ethoxide yields ethyl phenyl ether.
In the light of the above statements,choose the most appropriate answer from the options given below:

The correct statement regarding $X$ and $Y$ formed in the following reaction is
$(CH_3)_3COC_2H_5 \xrightarrow[\Delta]{HI} \text{halide } (X) + \text{alcohol } (Y)$

Ethoxybenzene on reaction with hot and concentrated $HI$ forms:
