a."Gentamicin has a longer half-life than other aminoglycosides."

Explanation:

Gentamicin is an aminoglycoside that binds to bacterial ribosomal proteins and causes the inhibition of the protein synthesis, killing the bacteria. The killing can continue for long periods after administrating the drug and even once that the concentrations of this one can no longer be detected in the plasma. That is the reason why this drug is given once a day.
