Frankly, there is no correct choice here.
Neither option B nor option C is a valid weakener, if we stay within the context of GMAT.
Option B: It says that unemployment rose when wages remained constant - So what? We are given in the passage that unemployment has risen since 1960. Most probably, there would be years when the wages were constant. So, this option statement cannot weaken the argument since we can already expect this from the given information.
