Swine vesicular disease is caused by an enterovirus in which viral family?

Explanation:
Swine vesicular disease virus is a picornavirus in the genus Enterovirus. Picornaviridae are small, non-enveloped, icosahedral RNA viruses with a positive-sense single-stranded genome. SVDV is genetically and antigenically linked to other enteroviruses (like polioviruses and coxsackieviruses), which is why it is classified within this family. The other options represent viruses with different properties: Caliciviridae are a separate family with distinct genome organization and serology, Reoviridae have segmented double-stranded RNA and a different replication strategy, and Togaviridae are enveloped positive-sense RNA viruses with different structural features. Thus, the correct family is Picornaviridae.
