Solution

The correct option is B
$(i)\Rightarrow d., (ii)\Rightarrow c., (iii)\Rightarrow b., (iv)\Rightarrow a.,$

B and T cells both recognize and help eliminate foreign molecules (antigens), such as those that are part of invading organisms, but they do so in different ways.

B cells secrete antibodies, proteins that bind to antigens.

T cells are the major driving force and the main regulators of the immune defense. Their primary task is to activate B cells and killer T cells.

B-cells are activated by the binding of antigen to receptors on its cell surface which causes the cell to divide and proliferate. Some stimulated B-cells become plasma cells, which secrete antibodies.
