Solution

The correct option is B Allergy
The exaggerated response of the immune system to certain antigens present in the environment (that are mostly non-pathogenic) is called allergy or hypersensitivity reactions. The substances to which such an immune response is produced are called allergens. IgE antibodies are generally produced during such a response. So, the correct option is 'Allergy'.
