Answer:
A) Viruses are also pathogenic
Step-by-step explanation:
A pathogen is an organism that is capable of causing a disease to another organism. Viruses, similarly to bacteria, are able to cause a diversity of diseases. However, they are considered non-living organisms because they fully depend on another cell to survive and reproduce. Therefore, they can only cause an infection if the organism's cells can support the replication of the virus. Moreover, to cause disease, the infecting virus has to overcome numerous "challenges", from physical barriers to host defenses.
Viruses can cause the following diseases:
- Common cold
- Influenza
- Herpes
- HIV
- Ebola
- Smallpox
- Rabies
amongst many others...
