Vedclass · Answer

(B) Allergies are an exaggerated immune response to certain antigens present in the environment.When an allergen enters the body, it triggers the immune system.Specifically, $P$ (Mast cells) are activated and release chemicals $Q$ (Histamine and Serotonin) into the bloodstream.These chemicals are responsible for the symptoms of an allergic reaction, such as itching, swelling, and redness.Therefore, the correct identification is $P = 	ext{Mast cells}$ and $Q = 	ext{Histamine, Serotonin}$.

Allergy is caused by the release of chemicals $Q$ from $P$. Identify $P$ and $Q$.
