B. Traces in history
- This statement is true. While viruses have been present throughout history and have had significant impacts on human health and evolution, they do not leave behind physical traces like fossils.

D. Nucleic acid

In summary, the correct answer to the question "Viruses do not have:" is option A. Fossil record.
