• D. i a o, ii d m, iii c l, iv b n

Answer 1

The correct option is A i d n, ii a o, iii b m, iv c l

White blood cells (WBCs) are of broadly divided into two types, agranulocytes and granulocytes. Granulocytes are further divided into neutrophils, basophils and eosinophils. Agranulocytes are further divided into lymphocytes and monocytes. Monocytes have kidney shaped nucleus. They are precursor of macrophages which are phagocytic in nature. Lymphocytes have large round nucleus. Two types of lymphocytes are B cells and T cells. B cells produce antibodies and T cells attack viruses and cancer cells. Basophils have twisted nucleus. These cells release heparin, histamine and serotonin as an immune response. Eosinophils have bilobed nucleus. These cells contain antihistamine which inhibits the activity of histamine released by basophils and mast cells.

Thus, the correct answer is option A.
