The answer is; B

Actually, viruses are considered nonliving things because they are unable to bear the characteristic of living things (such as respiration, reproduction, growth, excretion, and etcetera) on their own. They only infect host cells to ride on the cell's biochemical machinery to be able to reproduce. Once outside the cells, they are non-living.
