Metronidazole is selectively active against anaerobic
organisms because:
A. Aerobes have an active transport mechanism to pump it out of their cell
B. Only anaerobes reduce it to generate the
reactive nitro radical
C. It is rapidly inactivated in the presence of
oxygen
D. It binds to DNA of anaerobes with high affinity
