benzoic acid acidity?

[lostnconfused]

Can somebody please explain why compound B is more acidic than benzoic acid? I thought resonance took priority over induction in acidity.

You can't delocalize the charge into the benzene ring. Draw the resonance structures. The benzene ring also does not withdraw any electron density from the carboxylic acid. Thus, there is no resonance delocalization here - none that withdraws electron density from the carboxylic acid or stabilizes the conjugate base, anyway.
