Correct answer: B — Levofloxacin

NICE NG138 recommends avoiding beta-lactam antibiotics (penicillins, cephalosporins) in patients with a history of anaphylaxis. For severe community-acquired pneumonia (CAP) requiring IV treatment in such patients, a fluoroquinolone like Levofloxacin is a recommended option, often combined with an agent covering atypical pathogens if not already covered (though levofloxacin has atypical coverage). Clarithromycin alone is typically for mild-moderate CAP. Vancomycin is usually reserved for suspected MRSA. Ceftriaxone and Benzylpenicillin are beta-lactams and contraindicated.
