Which property of an enveloped virus most limits its survival outside the host?

  • A.It has no attachment proteins
  • B.It cannot infect animal cells
  • C.Its lipid envelope is easily disrupted
  • D.Its genome is always RNA

Answer: C

The envelope is host-derived lipid, and once it is damaged the glycoproteins it carries can no longer bring about attachment and entry. That fragility shapes how such viruses spread and how easily they are disinfected.
