The correct option is A Ofloxacin
Ofloxacin is a synthetic antibiotic that fights bacteria in the body. Ofloxacin is a broad-spectrum antibiotic against both Gram-positive and Gram-negative bacteria by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV, which is an enzyme necessary to separate replicated DNA, thereby inhibiting bacterial cell division. Thus, the correct answer is option A.
