Answer:
The correct answer will be option-C
Step-by-step explanation:
A biologist has always tried to distinguish the living things from non-living things and suggested eight unique features of the living world. The first characteristics feature is that living organism must be cellular, must contain genetic material and should reproduce and perform metabolic reactions.
Since a virus is a particle composed of genetic material and proteins enclosing it, therefore it is not considered a cellular entity and does not fulfill the criterion of a living world.
Thus, Option-C is the correct answer.
