Which of the following is the best description of the classical swine fever virus?

Explanation:
Classical swine fever virus is an RNA virus in the Pestivirus genus of the Flaviviridae family. It is not a DNA virus, nor is it placed in Coronaviridae or Aphthovirus. Pestiviruses show substantial genetic diversity, and different strains can have a wide range of virulence, which explains why disease severity can vary greatly depending on the strain. Therefore, the best description is an RNA virus in the Pestivirus genus with wide strain variability in virulence. The other options place the virus in the wrong family or genus or imply characteristics (like multiple serotypes or a DNA genome) that don’t fit CSFV.
