The presence of the chlorine atom on the benzene ring makes the second substituent enter at which position?

Nitrobenzene on further excessive nitration gives

In the reaction of $p-$chlorotoluene with $KNH_2$ in liquid $NH_3,$ the major product is :

The following reaction is:
$p-Nitrochlorobenzene + KOH \xrightarrow{\Delta} p-Nitrophenol + KCl$

Give chemical reactions for the following conversions:
$(1)$ Nitrobenzene from phenol
$(2)$ $p$-methylacetophenone from benzene

As compared with chlorocyclohexane, which of the following statements correctly apply to chlorobenzene?
$A$. The magnitude of negative charge is more on chlorine atoms.
$B$. The $C-Cl$ bond has partial double bond character.
$C$. $C-Cl$ bond is less polar.
$D$. $C-Cl$ bond is longer due to repulsion between delocalised electrons of the aromatic ring and lone pairs of electrons of chlorine.
$E$. The $C-Cl$ bond is formed using $sp^2$ hybridised orbital of carbon.
