Which antibiotic combination specifically includes a beta-lactamase inhibitor to combat beta-lactamase-producing bacteria?

Explanation:
Beta-lactamase enzymes produced by some bacteria break down beta-lactam antibiotics, making them ineffective. A beta-lactamase inhibitor neutralizes those enzymes, protecting the antibiotic so it can still kill the bacteria. Amoxicillin-clavulanate pairs amoxicillin with clavulanic acid, an inhibitor, which blocks beta-lactamase and allows the antibiotic to act against beta-lactamase–producing organisms. The other options lack an inhibitor or are not combined with one in this context, so they’re less effective against beta-lactamase producers. Hence, amoxicillin-clavulanate is the correct choice.
