Solution

The correct option is D Lysozyme.
A bacteriophage is a type of virus that infects bacteria. Bacteriophage genomes encode for lysozymes enzyme which plays the role in the lytic cycle. This enzyme helps in the release of virions by lysis of the host cells by digesting the host cell wall. Lysozyme also plays the role during infection where it bore a whole in host cellwall so that the bacteriopage can inject its genome into the host cytoplasm. Protease, urease and dehydrogenase are absent in bacteriophage. So, the correct answer is 'Lysozyme'.
