Answer:
The correct answer would be the disease.
A disease is defined as an abnormal or unnatural condition which negatively affects the function or structure of the part or the entire body of an organism. It should not be caused by any external injury.
It is mostly associated with specific signs and symptoms.
It can either be caused by external factors such as a pathogen or by internal dysfunction.
Pathogenic diseases may include typhoid, malaria, AIDS et cetera and diseases caused by internal dysfunctions may include allergies, autoimmunity, immunodeficiency et cetera.
