This answer is not correct. In order for a compound to be a base, it must be able to readily share a pair of electrons. The electron pair on the nitrogen atom is delocalized by resonance into the ring and are thus much less available to be shared. This compound is less basic than "a" because, if this electron pair is shared, the compound will no longer fit the "4n + 2" rule for aromaticity and will lose the aromatic stabilization energy.
