Cephalosporins shouldn't be an option because they also possess a beta-lactam ring as they belong to the Beta-Lactams family of antibiotics.

Both cephalosporins and penicillins have beta-lactam rings. The correct answer to that questions is options A and B. Why select B as the only answer?

Cephalosporin is a group of antibiotics and its broad classification. Question is specific asking one antibiotic which possess beta lactam ring.

Cephalosporin and penicillin both of them have beta-lactam ring.

The answer is A & B.

Barasa said: (Feb 1, 2017)  
This question is controversial, both penicillin (s) and cephalosporin (s) have a beta-lactam ring structure, which is why they are classified together structurally as beta-lactam antibiotics and functionally as cell wall synthesis inhibitors. Arun says it's about a specific antibiotic, initially, I thought so too but then the noun penicillin refers to both the group name and could also refer to a specific drug.
