Quizplus · Accepted Answer

Natural killer cells are a type of lymphocyte that destroy cancerous and virus-infected cells through a process called lysis. They do not rely on the presence of antibodies to recognize and attack target cells. Instead, they recognize changes in the surface proteins of infected or cancerous cells and induce programmed cell death in those abnormal cells. Therefore, the correct answer is D - cancerous cells and virus-infected cells.
