The most widely accepted definition of a virus is that it is a small infectious agent that replicates only inside the living cells of other organisms. Viruses are composed of genetic material, which can be either DNA or RNA, surrounded by a protein coat. Therefore, viruses are constructed from a protein wrapped around DNA or RNA.

C) is incorrect because viruses do not have any metabolic processes, let alone photosynthesis.
