Which term is an antibiotic in the list?

• A. Caine
• B. Oxacin
• C. Ide
• D. Dine

Answer: (B)

Suffixes in drug names often hint at their class. Oxacin denotes quinolone antibiotics, such as ciprofloxacin, which kill bacteria by inhibiting DNA gyrase and topoisomerase IV, blocking DNA replication. The other endings correspond to non-antibiotic drugs, like -caine for local anesthetics and -ide or -dine for other drug types. So Oxacin is the antibiotic term in this list.
