Which of the following compounds is formed when ether is dissolved in cold concentrated sulphuric acid?

Etherates are:

The major product of the following reaction is

Identify $A$ and $B$ in the following reaction: $C_6H_5CH_2-O-C_6H_5 + HI \rightarrow A + B$

Match the products of the reaction with anisole in Column-$I$ with the reagents in Column-$II$. Find the correct reagent for the product in Column-$I$ from Column-$II$.

Column-$I$ (Product)	Column-$II$ (Reagent)
$A$. Mainly $p$-bromoanisole	$i$. Anhydrous $AlCl_3$,$CH_3COCl$
$B$. $4$-nitroanisole	$ii$. $CH_3Cl$,anhydrous $AlCl_3$ in $CS_2$
$C$. $4$-methoxytoluene	$iii$. $Br_2$ in ethanoic acid
$D$. $4$-methoxyacetophenone	$iv$. Mixture of conc. $H_2SO_4$ and $HNO_3$

Which products are obtained when methoxy ethane is heated with $HI$?
