- A. an idiosyncratic response to food.
- B. an autoimmune disorder.
- C. a Type I hypersensitivity response.
- D. an example of immunosuppression.
Correct Answer: C
Rationale: Idiosyncratic response means it occurs because of an unknown reason. This response to something the body has been exposed to before is not unknown. Autoimmune disorders are ones in which the body attacks self-cells. This example is an outside antigen. Type I hypersensitivities are those that occur when the body, previously sensitized to a substance, is then exposed a second time and reacts. Immunossuppression occurs when the immune system is not working. Mr. Rowe's immune system responded to the antigen, so it is not suppressed.
