Detailed explanation-1: -Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Detailed explanation-2: -Which of these best describes a virus? a protein capsid and genetic material, in the form of either RNA or DNA.
Detailed explanation-3: -First seen as poisons, then as life-forms, then biological chemicals, viruses today are thought of as being in a gray area between living and nonliving: they cannot replicate on their own but can do so in truly living cells and can also affect the behavior of their hosts profoundly.
Detailed explanation-4: -On the basis of structure, which statement justifies that viruses are non-living. Viruses lack cells organelles.
