A particle can infect humans and make them sick. It attaches to a host cell and injects its RNA, which the host uses to make proteins for the particle. This particle cannot reproduce on its own and can only copy itself by using the machinery of the host. A particle can infect humans and make them sick.

This particle cannot reproduce on its own and can only copy itself by using the machinery of the host. Which explains whether the particle described is a virus or a cell?

A.
The particle is a cell because it does not make proteins and cannot reproduce by itself.
B.
The particle is a virus because it makes proteins but cannot reproduce by itself.
C.
The particle is a cell because it has genetic information and attaches to other cells.
D.
The particle is a virus because it has genetic information and can infect humans.
