(c) As part of both extrinsic and intrinsic pathways(Ref: Robbins 9th/pg 118-119; 8th/pg 119)Activated factor IX along with factor VIIIa (Intrinsic pathway) & factor VIIa (extrinsic pathway), converge to activate Factor X to Xa is necessary for conversion of prothrombin to thrombin (common pathway)
