Which best explains why viruses are not classified by Linnaean taxonomy?
A) Viruses do not contain any genetic information or a cell wall.
B) Viruses share many characteristics with several of the kingdoms.
C) Viruses cannot reproduce outside a host cell and are therefore nonliving.
D) Viruses lack a protein coat and any metabolic activity.

C) Viruses cannot reproduce outside a host cell and are therefore nonliving.
