Explanation Explanation of correct answer: Option (d) is given as, ‘antibodies’. In the immune system, the white blood cells are formed to provide the defense against the foreign antigens hence these are known as the soldiers’ cells of the human body. These are formed by the hematopoietic stem cells in the bone marrow and get mature in the thymus. The white blood cells do not include the secretions and products. Antibodies are the product and protein secretion of the plasma cells in order to attack the invaders and hence cannot come under the white blood cells. Hence, this is a correct option. Explanation for incorrect answer: Option (a) is given as, ‘phagocytes’...
