b) hypertonic
c) isotonic

b

hyper means more than and hypo means less than like hyperthermia (too hot) or hypothermia (too cold)

The correct answer is Fibrin. 
Fibrin is a fibrous, non-globular protein involved in the clotting of blood. It is formed by the action of the protease thrombin on fibrinogen which causes it to polymerize. The polymerized fibrin together with platelets forms a homeostatic plug or clot over a wound site.
