What is the mechanism of action used by cephalosporins in the treatment of bacterial infections?

A. Inhibition of protein synthesis is the mechanism of action for other classes of antibiotics, such as tetracyclines and macrolides. B. Inhibition of DNA replication is characteristic of fluoroquinolones. C. Cephalosporins work by inhibiting cell wall synthesis, leading to bacterial lysis and death. This mechanism is critical for their effectiveness against a wide range of bacterial infections. D. Inhibition of folic acid synthesis is primarily associated with sulfonamides.
