Correct answer: B. Lack metabolic machinery
- A. Too small
- B. Lack metabolic machinery
- C. Have no cell wall
- D. All of these
Explanation
Option B is correct. Viruses do not replicate on their own because they are not living organisms and lack the metabolic machinery. In order for a virus to replicate, it needs to infect a host cell. The virus's genetic material is then injected into the host cell, and the host cell's machinery is used to replicate the virus's genome and produce new virus particles.
