If the virus infects a host cell and replicates, the new viruses will contain A. influenza A virus protein coats and poliovirus genetic material B. poliovirus protein coats and influenza A virus genetic material C. influenza A virus protein coats and influenza A virus genetic material D. poliovirus protein coats and poliovirus genetic material

It will depend on the type of virus that infects the host's cells. For example, if it is a poliovirus, the answer will be "D. poliovirus protein coats and poliovirus genetic material"

Explanation:

A virus is composed of genetic material encapsulated by a protective coat protein (capsid). The genetic material of a virus can be either DNA or RNA and single-strand or double-stranded (either DNA or RNA). Moreover, the capsid may be surrounded by an additional spikey coat known as envelope. During infection, a virus invades the host´s cells to replicate both its genetic material and its proteins (they use host cellular machinery to synthesize new viral proteins). Depending on the type of virus, they can integrate and replicate its genetic material into the host genome (DNA viruses and RNA retroviruses) or replicate its genetic material outside the host genome (RNA viruses in general).
