Answer:
The correct answer is b cephalosporin
Step-by-step explanation:
Cephalosporin is a drug the inhibit the cell wall formation in bacteria.Cephasporin basically inhibits the catalytic activity of trans peptidase enzyme that play an an important role during trans peptidation reaction which deals with peptide cross linkage with polysaccharide molecules resulting in the formation of chemical structure of bacterial cell wall.
As the trans peptidase enzyme is inhibited bacterial cell wall synthesis is blocked.
