\(-\mathrm{Cl}\) shows \(+\mathrm{M}\) and \(-\mathrm{I}\) but inductive effect dominates.
\(-\mathrm{NO}_2\) shows \(-\mathrm{M}\) and \(-\mathrm{I}\).
Electrophilic substitution \(\alpha \frac{1}{-\mathrm{M} \text { and }-\mathrm{I}}\)
\(\alpha+\mathrm{M} \text { and }+\mathrm{I}\)
Hence, order is \(\mathrm{B}>\mathrm{A}>\mathrm{C}>\mathrm{D}\).
