Kerri purchased a new plant that she thought was just perfect. Unfortunately, she developed a rash after handling the plant. The rash is most likely the result of
A) haptens derived from the plant combining with skin molecules and then stimulating an immune response.
B) haptens binding directly to helper T cells and stimulating an immune response.
C) haptens damaging blood vessels in the skin, resulting in increased permeability of these blood vessels.
D) haptens interacting with existing antibodies and destroying Kerri's adaptive immunity.
Haptens
Small molecules that elicit an immune response only when attached to a larger carrier such as a protein.
Immune Response
The Immune Response is the body's defense mechanism against foreign pathogens, involving both innate and adaptive immune elements to neutralize and eliminate these invaders.
- Gain insight into the duties and mechanisms of adaptive immunity cells.
- Elucidate the particularity of the immune response and its guiding processes aimed at specific pathogens.

Final Answer :
A
Explanation :
Haptens are small molecules that, when combined with larger proteins, can elicit an immune response. In this scenario, the plant likely contains haptens that bind to skin molecules, forming a complex that the immune system recognizes as foreign, leading to an immune response manifested as a rash. This process does not involve direct binding to T cells, damaging blood vessels, or destroying adaptive immunity, making the other options incorrect.
