The correct answer is **b. B cells**.

### Explanation
Antibody-mediated immunity, also known as humoral immunity, primarily involves B cells, which are a type of white blood cell. When B cells encounter an antigen (a substance that can provoke an immune response), they can differentiate into plasma cells. These plasma cells produce antibodies tailored to specifically bind to that antigen.

Antibodies are crucial for identifying and neutralizing pathogens such as bacteria and viruses. Once B cells are activated and produce antibodies, they also create memory cells that remain in the body, enabling a quicker and more effective response if the same antigen is encountered in the future. Other cell types listed in the options, such as NK cells, helper T cells, cytotoxic T cells, and suppressor T cells, play various roles in the immune response but do not directly produce antibodies.
