Which of the following compounds reacts slower than benzene in electrophilic bromination?

Match the following reactions given in Column-$I$ with their respective names in Column-$II$:

Column-$I$	Column-$II$
$(i)$ $\text{Benzene} + \text{Conc. } HNO_3 + \text{Conc. } H_2SO_4 \rightarrow \text{Nitrobenzene}$	$(A)$ $\text{Halogenation}$
$(ii)$ $\text{Benzene} + Cl_2 \xrightarrow{\text{Anhy. } AlCl_3} \text{Chlorobenzene}$	$(B)$ $\text{Nitration}$
$(iii)$ $\text{Benzene} + CH_3Cl \xrightarrow{\text{Anhy. } AlCl_3} \text{Toluene}$	$(C)$ $\text{Friedel-Crafts acylation}$
$(iv)$ $\text{Benzene} + CH_3COCl \xrightarrow{\text{Anhy. } AlCl_3} \text{Acetophenone}$	$(D)$ $\text{Friedel-Crafts alkylation}$

What are the various steps of electrophilic substitution of benzene?

Assertion : Rates of nitration of benzene and hexadeuterobenzene are different.
Reason : $C-H$ bond is stronger than $C-D$ bond.

Which compound is formed when benzene is boiled with concentrated $HCl$?

Decide the correct order of reactivity of the following compounds towards electrophilic aromatic substitution (halogenation) with $(Cl_2 + AlCl_3)$:
$I$: Phenyl benzoate $(C_6H_5COOC_6H_5)$
$II$: Toluene $(C_6H_5CH_3)$
$III$: Ethylbenzene $(C_6H_5CH_2CH_3)$
$IV$: Benzene $(C_6H_6)$
