Answer:

C. Viruses require cells to survive and reproduce

Explanation:

Viruses are considered non-living organisms because they are not able to survive and reproduce on their own. Instead, they select a cell, also known as a host cell, where it can reproduce. Once the virus finds this host, it injects it genetic material and takes over its functions.

Therefore, they highly depend on another cell to survive and reproduce. This could lead scientists to think that viruses evolved after cells, as they wouldn't be able to survive without them.
