C. Viruses cannot reproduce outside a host cell and are therefore nonliving. Being able to reproduce is required in classification by Linnaean taxonomy.

@Vikas_garg Linnaeus didn't even know about viruses when he started naming things. Sure, he knew about diseases, but viruses themselves were first discovered a century or so after his death.
