Answer:
C. The substance does not directly harm tissues and is not a pathogen, but nevertheless triggers an inflammatory response.
Explanation:
When a person is allergic to a substance, his or her immune system recognizes a harmless substance, such as components in food, pollen, or dust, as a treat. As a consequence, it starts an immune response that leads to inflammation. The substance that starts the allergic reaction is called an allergen, and it is not a pathogen because it is not a real threat to the body since it does not infect cells. When the allergen enters the body, it binds to antibodies that are in contact with a special type of cell. These specific cells will release a substance known as histamine. Histamine will produce an inflammatory reaction affecting different tissues in our body. For example, it can make us sneeze, have a running nose, swelling parts of our body, have itchiness and redness, amongst others.
