The correct option is B IgE
Allergies are hypersensitive reactions of the immune system to certain allergens or antigens. Most people who get stung by an insect show a minor reaction, which include redness, itching, swelling etc. However, in some cases, this sting can lead to severe allergic reactions and even death. If someone is allergic to the bee stung and his body’s immune system over-sensitizes the allergen as a foreign substance and produces a high amount of IgE antibodies. This high IgE response leads to the release of many more chemicals like histamines and inflammatory chemicals that cause the severe allergic reactions.
