I think it's definitely C) Beta-lactamase. That's the classic mechanism for penicillin resistance.

I believe it's Penicillin binding proteins (PBPs) that are responsible for resistance to dicloxacillin.

I agree with Wenona, Beta-lactamase can break down dicloxacillin.

I think the mechanism of resistance of dicloxacillin is Beta-lactamase.

Hmm, that makes sense too. Beta-lactamase can definitely break down dicloxacillin.

I disagree, I believe it is because of beta-lactamase production by bacteria.

I think the mechanism of resistance of dicloxacillin is due to mutations in M protein.
