Virus is not an organism is the correct answer.

Explanation:

An organism is a living thing. Plants and animals are also organisms. They are biotic and living part of the environment, rocks and water cannot be considered as a living organism because they are nonliving beings. Organisms need five basic needs air, water, nutrients and energy to stay alive. There is still no consensus about whether we should consider a virus as living or not living being. They contain nucleic acid, protein and also evolve but they exist in two different phases, one is the dormant phase and the other is a live phase. When the virus is inside a living organism it behaves like an organism.
