Answer 1

The correct option is C Both I and II

Pathogens are microorganisms that have the potential to cause infectious diseases. Viruses, bacteria, protozoans and fungi are all potential pathogens.

Pathogens invades the body through the openings, which uses the host body’s resources, multiplies and causes severe infectious disease. Most pathogens are able to avoid the immune responses of the host, triggering associated illnesses. The pathogen then utilizes the host body’s resources to replicate before exiting and spreading to a new host (like a virus). During the process of multiplying themselves (pathogens) damages the body cells, interfere with their normal activities.
