The correct answer will be option-B
A virus is an infectious pathogen which is composed of a genetic material enclosed in a structure made up of protein.
They are the topic of debate whether they are living or non-living. Their living feature is that they contain the genetic material which could be either DNA or RNA. Since the presence of nucleic acid as genetic material is one of the characteristic features of the living organism, therefore, they can behave like a living organism.
Thus, Option-B is the correct answer.
