Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. (Thrombosisis the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system.) They also contain the vasodilator histamine, which promotes blood flow to tissues.
So, the correct answer is 'Heparin secretion for preventing thrombosis'.
