Quizplus · Accepted Answer

Antibody-dependent cell-mediated cytotoxicity (ADCC) occurs when antibodies attached to target cells (such as virally infected cells) recruit natural killer (NK) cells. The NK cells then bind to the antibody's Fc region and induce apoptosis in the target cell, effectively eliminating the infected cell. This process does not directly involve antigen presentation, complement fixation, neutralization, or opsonization, making option A the correct answer.
