A patient is being treated for a bacterial infection with amoxicillin, but the infection is resistant due to bacterial production of beta-lactamase enzymes. To overcome this resistance, which of the following agents would most likely be added to the amoxicillin regimen?

✓ Correct Answer: Option B

Clavulanic acid is a beta-lactamase inhibitor that irreversibly binds to and inactivates bacterial beta-lactamase enzymes. When co-administered with amoxicillin, it protects the antibiotic from degradation, thus restoring its efficacy against resistant bacteria.
