As pt is sensitive to penicillin And cephalosporins are best for LRTI Gram positive infection responds best to macrolides my preference would azithromycin

The correct answer is, "C. Macrolide. Marcolides are used to treat gram-positive bacterial infections and are used in patients with penicillin allergies. In addition, usually if a patient is allergic to penicillin there is an increased chance they are allergic to cephalosporin....therefore it would not be used as well."

In bacterial pneumonia allergic to penicillin best choice is Macrolide group of drugs since these are tissue directed antibiotics known for deep penetration of tiseue

A is right answer
