Is there a mistake with this question? If not, why is the answer choice A and not C?

 

[FeralisExtremum]

The lone pair on the Nitrogen atom in answer C is resonance stabilized by the aromatic ring. There's no aromatic stabilization going on in A, so it's a much stronger base.

Oh okay, I get it. Without resonance the lone pair is the least stable and thus the most reactive.

That really helped, thanks Feralis!

Just remember acids need to have most stable and bases least stable
