The correct answer is: C. Both A and B
Viruses are called that because they are viruses, which means they are non-living particles that can replicate only inside living cells. They can copy themselves and spread from one cell to another, causing disease.
Option A is incorrect because viruses are not actually living things. They do not have cells or any of the other structures that are necessary for life.
Option B is incorrect because viruses cannot replicate on their own. They need to infect a living cell in order to replicate.
Option D is incorrect because viruses are both viruses and they can copy themselves and spread.
