Answer:
C. Viruses require cells to survive and reproduce
Explanation:
Viruses are considered <u>non-living organisms because they are not able to survive and reproduce on their own</u>. Instead, they select a cell, also known as a <em>host</em> cell, where it can reproduce. Once the virus finds this host, it injects it genetic material and takes over its functions.
Therefore, <u>they highly depend on another cell to survive and reproduce</u>. This could lead scientists to think that viruses evolved after cells, as they wouldn't be able to survive without them.
