Explanation:

Viruses are obligate intracellular parasites, which means they must have a host cell to replicate. They cannot carry out metabolic processes or reproduce on their own. The other options about their evolution from small cells that parasitized large cells or requirements for multicellular hosts are not correct definitions of "obligate intracellular parasite."

Answer:

Viruses must have a host cell.
