Match column $-I$ and column $-II$ with the correct electronic effect relation:

Column $-I$	Column $-II$
$(i)$ $C_6H_5NH_2$	$(p)$ $-R$ effect
$(ii)$ $C_6H_5OH$	$(q)$ $+R$ effect
$(iii)$ $C_6H_5NO_2$	$(r)$ $+I$ effect
$(iv)$ $CH_3CH_2Cl$	$(s)$ $-I$ effect

(A) $(i) - (q, s)$; $(ii) - (q, s)$; $(iii) - (p, s)$; $(iv) - (s)$.
Explanation:
$(i)$ $C_6H_5NH_2$: The $-NH_2$ group has a lone pair on nitrogen,showing $+R$ effect,and is more electronegative than carbon,showing $-I$ effect.
$(ii)$ $C_6H_5OH$: The $-OH$ group has lone pairs on oxygen,showing $+R$ effect,and is more electronegative than carbon,showing $-I$ effect.
$(iii)$ $C_6H_5NO_2$: The $-NO_2$ group is electron-withdrawing,showing $-R$ effect,and is highly electronegative,showing $-I$ effect.
$(iv)$ $CH_3CH_2Cl$: The $-Cl$ atom is electronegative,showing $-I$ effect. It does not show resonance with the alkyl group.
