Answer:
C. Viruses do not consist of cells; they also lack cell membranes, cytoplasm, ribosomes, and other cell organelles.
Step-by-step explanation:
Viruses are only composed of a couple things: strands of nucleic acid that can be DNA or RNA, a protein coat called a capsid, and potentially a glycolipid coat to protect the outside.
There are no organelles, nor are there cells. Keep in mind that a virus is nonliving, so D is utterly wrong.
