These groups activate benzene ring for further substitution

(A) $-{\mathrm{NH}}_2$  (B) $-\mathrm{OH}$  (C)$-{\mathrm{CH}}_3$   (D) $-{\mathrm{NO}}_2$

the correct answer is 

-NH₂ and -OH by delocalizing electron pair into benzene ring activates towards EAS. +M groups

-CH₃ due to hyperconjugation activates towards EAS

-NO₂ is -M effect group deactivates towards EAS
