Correct answer only. Please.

O Viruses

The correct answer is "Viruses." Viruses require a host to reproduce.

The correct answer is O Viruses.

Viruses require a host to reproduce. They are considered obligate intracellular parasites, meaning they can only replicate and multiply within a host cell. Viruses infect a variety of organisms, including humans, animals, plants, and even bacteria. Once inside a host cell, viruses hijack the cell's machinery and use it to produce more viral particles. These new viral particles can then go on to infect other host cells. Without a host, viruses are unable to reproduce.
