ANSWER: C.Serotonin release from platelets

EXPLANATION:

Hemostasis is a process which causes bleeding to stop

it has 3 steps 1.vasoconstriction 2.platelet plug formation 3.blood coagulation or formation of fibrin clot

Vasoconstriction in which the smooth muscle in the vessel walls undergo intense contractions and increases blood pressure of affected vessel wall

if the vessels are small,spasms compress the inner walls together and may able to stop bleeding completely which is stimulated by the platelets from serotonin.
