Solution

The correct option is C $I < I I < I I I < I V$
In Electrophilic aromatic substitution reaction, the electrons donating group is favoured over electron withdrawing group.
$- N H_{2} > + - N R_{3} > - O - O | | C - C H_{3} > - N H C O C H_{3}$
This is the required order of electrophilic aromatic substitution.
