Answer:
1. type IV hypersensitivity: delayed-type hypersensitivity.
2. type I hypersensitivity: IgE
3. type II hypersensitivity: IgG
4. type III hypersensitivity: immune complexes
Step-by-step explanation:
Type IV hypersensitivity is cell mediated hypersensitivity rather than antibodies as in all other types of hypersensitivities. It is also known as delayed type hypersensitivity because it usually respond in 2-3 days via T-Lymphocytes rather than antibodies like IgE or IgG. So we can say that in option 5 is mismatched as it relates type IV to IgG antibodies.
