Answer:
B. Viruses must commandeer the mechanisms of a host cell in order to reproduce
Explanation:
Virus is an organism that is incapable of replicating on its own without infecting a living host cell. A viral cell is dependent on a living host to replicate and express its genes. Hence, the infection cycle of a virus is its reproductive life cycle.
Other living organisms e.g plant, bacteria, fungi etc. have the ability to reproduce i.e. multiply on their own through asexual or sexual means. However, on the contrary, a virus must infect a living host, hijack the replicational abilities of the host cell in order to reproduce. Based on this, a virus employs a lysogenic or lytic cycle or both on its host to reproduce.
