"Viruses are nonliving infectious agents."

Reason: Viruses are acellular particles (genetic material in a protein coat) and are obligate intracellular parasites — they require a host cell to replicate. They are not killed by antibiotics (antivirals are used instead) and are not cellular like bacteria.
