(c)Assertion is correct but Reason is incorrect.
(d)Both Assertion and Reason are incorrect.

Answer 1

A pathogen can also be mentioned as an infective agent or just a germ that will produce disease. A parasite is an organism that has undergone contact with another organism to harm the host organism.

Complete answer:
Parasites and pathogens are two sorts of organisms that will be dangerous to hosts. Both parasites and pathogens are disease-causing agents within host organisms. Both of them are particular to the host and have high multiplication rates.
The major difference between a parasite and a pathogen is that parasites are often a category of pathogen whereas pathogens are disease-causing organisms within the host. However, not all parasitic organisms are pathogens.
Examples of pathogens include viruses, bacteria, and fungus.
Parasitism is a symbiotic relationship between species, in-depth, and protracted long-term biological interaction between a parasite and its host. Where the parasite lives on the host but does not kill them. The majority of the parasites are causing harm to the host and that they may reduce the survival growth and reproduction of the host.
Examples of parasites include Protozoans and helminths. The host organism might be an animal, plant, or microorganism.
So, the correct answer is ‘Assertion is correct but Reason is incorrect’.

Note: -Parasites lower host fitness and increase their own fitness by exploiting hosts for resources necessary for their survival. The scientific study of parasites is called Parasitology.
-Humans can be infected with many types of pathogens such as prions, viruses, bacteria, and fungi. The study of disease which will include these pathogens is named pathology.
