The correct option is E Basophils
Basophils are granulocytes i.e., they contain large cytoplasmic granules in the cell nucleus and it stores histamine (a vasodilator), a chemical which is secreted by the cells when stimulated, which promotes blood flow to tissues. Also, basophils contain anticoagulant heparin, which prevents blood from clotting too quickly.
Thus, the correct answer is option (E), 'Basophils'.
