Question

Cells involved in immune mechanism are

• A. Erythrocytes
• B. Lymphocytes
• C. Eosinophils
• D. Thrombocytes

Answer 1

The correct option is B Lymphocytes

A lymphocyte is one of the subtypes of white blood cell in a vertebrate's immune system. Lymphocytes include natural killer cells (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody-driven adaptive immunity). They are the main type of cell found in lymph. Lymphocytes are involved in the activation of the immune system.

So, the correct answer is 'Lymphocytes'.
