Verified step by step guidance1
Step 1: Understand the definitions of each option. A prion is an infectious protein, not a virus.
Step 2: Recognize that a viroid is a small infectious RNA molecule that affects plants, but it is not classified as a virus because it lacks a protein coat.
Step 3: Identify that a bacteriophage is a virus that specifically infects bacteria, making it a true virus.
Step 4: Know that a plasmid is a small, circular DNA molecule found in bacteria, but it is not a virus.
Step 5: Conclude that among the options, the bacteriophage is the correct choice as it fits the classification of a virus.
