The correct increasing order of basic strength of amine is:
(A) \(CH_5NH_2<NH_3 <CHCH_2NH_2 < C_2H_5NH_2 < (CH)_2NH \)
(B) \(NH_3 <C_6H_5NH_2 < CHCH_2NH_2 < C_2H_5NH_2 < (C_2H_5)_2NH \)
(C) \(C_6H_5CH_2NH_2 <C_6H_5NH_2 < NH_3 <C_2H_5NH_2 < (C_2H_5)_2NH \)
(D) \(C_2H_5NH_2 < (C_2H_5)_2NH < C_6H_5NH_2 < NH_3\)
