Which of the following is a macrolide antibiotic?

Explanation:
Macrolide antibiotics work by binding to the 50S ribosomal subunit of bacteria, blocking protein synthesis and stopping bacterial growth. Azithromycin is a macrolide, a group that also includes erythromycin and clarithromycin. This class is commonly chosen for respiratory infections or when penicillin allergy is a concern. Amoxicillin is a penicillin-type beta-lactam, not a macrolide. Ciprofloxacin is a fluoroquinolone that inhibits DNA gyrase, not a macrolide. Doxycycline is a tetracycline that inhibits the 30S ribosomal subunit, also not a macrolide.
