Verified step by step guidance

Understand the role of cytotoxic T cells in the immune system. These cells are a type of lymphocyte that play a crucial role in the adaptive immune response.

Recognize that cytotoxic T cells, also known as CD8+ T cells, are primarily responsible for directly killing infected or cancerous cells.

Differentiate between the functions of different immune cells: Cytotoxic T cells directly kill target cells, while B cells are responsible for producing antibodies.

Consider the other options: Activating B cells to produce antibodies is primarily the role of helper T cells, not cytotoxic T cells.

Remember that cytotoxic T cells do not produce antibodies or suppress the immune response; their main function is to eliminate cells that are infected or have become cancerous.
