Which pathogen is non-living?
A
Virus
B
Bacteria
C
Fungi
D
Parasite
Explanation: 

Detailed explanation-1: -Viruses are responsible for some of the world’s most dangerous and deadly diseases, including influenza, ebola, rabies, smallpox and COVID-19. Despite their potential to kill, these potent pathogens are in fact considered to be non-living, as alive as the screen that you are reading this article on.

Detailed explanation-2: -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-3: -Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Detailed explanation-4: -Nonliving traits include the fact that they are not cells, do not contain cytoplasm or cellular organelles, and do not have their own metabolism, therefore they must multiply utilising the metabolic machinery of the host cell. Another crucial feature of a virus is its ability to crystalize.
