JEE Main Chemistry question

The negative charge developed on nitrogen (in the resonance hybrid of the conjugate acid) makes a compound more basic; also, a secondary amine is more basic than a primary amine (due to the effect of the extra alkyl group), while in an amide the lone pair remains less available due to delocalisation by resonance. This set of facts is best summarised by the statement:

• (A)Resonance-delocalisation of the N lone pair (as in an amide) reduces basicity, while inductive electron donation (as from extra alkyl groups in a 2° amine) increases itCorrect
• (B)All nitrogen-containing compounds are equally basic
• (C)Amides are more basic than amines
• (D)1° amines are always more basic than 2° amines
