The correct definition of a host in this context is:

Any living organism that can be infected by a virus.

In biological terms, a host is an organism that harbors a parasite, pathogen, or symbiont, providing it with nutritional and other forms of support. In the case of viruses, the host cell is where the virus replicates and carries out its life cycle.
