The correct option is C Endolysins
Endolysins are the peptidoglycan hydrolases that are produced by bacteriophages to hydrolyse peptidoglycan cell wall of host bacteria during lytic cycle. Proenzymes are the inactive enzymes. Phage-lysozymes are the enzymes that disrupt peptidoglycan cell wall of host bacteria to facilitate infection or release of virions; endolysin is phage-lysozymes involved in rupture of the bacterial cell for the release of viral particles. Phage proteins include all proteins encoded by phages. Thus, the correct answer is option C.
