Iteru [2.4K]

Answer:

The correct answer is A  bacteriophages inject only DNA into the bacteria.

   After doing that(creating a hole) bacteriophage inject its DNA inside the bacterium.

   The injected DNA undergo gene expression by utilizing the gene expression machinery of bacteria which ultimately result in the formation of coat protein.The DNA is then packed within the coat protein to form progeny phages.The progeny phages then disrupt the cell wall and get released from the bacterium in search of a new host.
