The correct order of reactivity in electrophilic substitution reaction of the following compounds is :

– CH₃ shows +M and +I.
– Cl shows + M and – I but inductive effect dominates.
– NO₂ shows –M and – I.
Electrophilic substitution $\begin{array}{l}\mathrm{\alpha }\frac{1}{-\mathrm{M}\text{ and }-\mathrm{I}}\\ \mathrm{\alpha }+\mathrm{M}\text{ and }+\mathrm{I}\end{array}$
Hence, order is B > A > C > D.
