• C. Mast cells
• D. Helper T-cells

Answer 1

Answer: (D)

Helper T-cells

B cells, also known as B lymphocytes are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system by secreting antibodies. B-cells bind to an antigen, receive help from a cognate helper T cell and differentiate into a plasma cell that secretes large amounts of antibodies.

So, the correct answer is 'Helper T-cells'.
