The first answer is the correct one
Human factors psychology is a branch of experimental psychology often associated with industrial/organizational psychology because it concentrates on the interaction of people and machines. Good human factors engineering can make a product convenient and easy to use, rather than frustrating and confusing.
What is Human Factors psychology?
Human Factors as a discipline was stimulated by pilot errors that cost many lives during World War II. Analysis of flying accidents revealed that many were due to the confusing layout of instruments in airplane cockpits. Pilots were faced with a bewildering array of dials and gauges in the cockpit, yet they were expected to keep track of all pertinent information and respond appropriately in emergencies. Human Factors psychologists helped to identify problems in cockpit design. They attempted to design instrument panels that were clear and easy to use for humans.
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.

I would have studied pattern of movement of affected kids. The common pool to which all these kids visited can be the infectious one. Also one can test the pathogen in infected kinds, and look for similar pathogen in pool water through testing.
