Final answer:
The Rhinovirus belongs to the Picornaviridae family, which is responsible for causing the common cold and is transmitted through direct contact and aerosols.
Step-by-step explanation:
The family to which the Rhinovirus belongs is the Picornaviridae. Rhinoviruses are a common cause of the common cold and are transmitted via direct contact, aerosols, or environmental surfaces. They are identified as non-enveloped ssRNA(+) viruses that are members of the Picornavirus genus, thus falling under the Picornaviridae family. It is crucial to differentiate between the genus and the family: 'EnteroVIRUS' is a genus within the Picornaviridae family, while 'EnteroVIRIDAE' and 'PicoRNAVIRUS' are not valid classifications when referring to the viral family. Therefore, the correct answer to the question is a) Picornaviridae.
