Solution

The correct option is A Virus that attacks bacteria
A bacteriophage is a virus that infects and replicates within a bacterium. Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome. Phages replicate within the bacterium following the injection of their genome into its cytoplasm. They attack the bacteria and lyse them.
Therefore, the correct answer is option A.
