Solution

The correct option is A IgE
Whenever a potential allergen enters the body, IgE is released. The allergen then binds to these immunoglobulins on the surface of immune cells called basophils and mast cells. This binding results in the release of chemicals like histamine, serotonin, etc. that cause various inflammatory reactions in the body. So, the correct option is 'IgE'.
