Which condition best exemplifies a Type II hypersensitivity reaction?

Explanation

Type II hypersensitivity reactions are characterized by antibody-mediated destruction of cells. Autoimmune hemolytic anemia is a classic example where antibodies target red blood cells, leading to their destruction. In contrast, the Arthus reaction is a Type III hypersensitivity, systemic lupus erythematosus involves multiple hypersensitivity types, and contact dermatitis is a Type IV hypersensitivity.
