Which of the Following Is the Correct Explanation of Desensitization

Which of the following is the correct explanation of desensitization?

A) In desensitization, a person is injected with dilute preparations of an allergen, causing their immune system to produce IgE against that allergen. The IgE antibodies protect the patient by binding to the antigen, coating it and facilitating its removal before it can attach to bound IgG on mast cells or basophils.
B) In desensitization, a person is injected with dilute preparations of an allergen, causing their immune system to produce multiple varied antibodies against that allergen. These antibodies protect the patient by binding to the antigen, coating it and destroying it before it can attach to bound IgE on mast cells or basophils.
C) In desensitization, a newborn baby is exposed to multiple common allergens, stimulating the infant's immune system to produce antibodies against those allergens. The antibodies protect the child later in life by binding to any antigens they come into contact with, tagging them for destruction before they cause an allergic response.
D) In desensitization, a pregnant woman is injected with dilute preparations of an allergen, causing their immune system to produce IgG against that allergen. The IgG antibodies cross the placenta, protecting the fetus by preventing it from being exposed to those allergens after birth.
E) In desensitization, a person is injected with dilute preparations of an allergen, causing their immune system to produce IgG against that allergen. The IgG antibodies protect the patient by binding to the antigen, coating it and facilitating its removal before it can attach to bound IgE on mast cells or basophils.
