Which of the following descriptions correctly identifies a main structural difference between viruses with envelopes and viruses withoutenvelopes?O A. Only viruses with envelopes package their genetic material by engulfing it.O B. Only viruses without envelopes interact with receptor proteins on the surface of the host cell.O. Only viruses without envelopes can release their genetic material into the cytoplasm of the host.O D. Only viruses with envelopes have their contents enclosed by a membranous layer containing lipids.
