Answer:

Type II Hypersensitivity

Explanation:

Hypersensitivity reactions are exaggerated immune responses that are detrimental to the host and Type II Hypersensitivity is also known as antibody-mediated hypersensitivity.

This type of hypersensitivity reaction involves humoral immunity and it occurs when IgM or IgG antibodies bind to cell surface antigens which lead to complement activation or IgG/FcγR interaction.

Clinical manifestations of Type II hypersensitivity responses include trans- fusion reactions, hemolytic disease of the newborn, autoimmune reactions to cellular antigens or tissues and hyperacute rejection of transplanted tissue.

Sample Response:

Bacteria are helpful because they produce oxygen, which our bodies need to breathe, and they help us to digest the food we eat.

Bacteria are harmful because they can cause tooth decay and illnesses that can be either common or quite serious.

This is a sample response, so it's 100% correct. Peace!
