What rich source of coagulation factors is provided by fresh frozen plasma?

Fresh frozen plasma is indeed a rich source of coagulation factors, which makes it particularly valuable in both clinical and surgical settings. It contains various proteins essential for the blood clotting process, including Factors I (fibrinogen), II (prothrombin), V, VII, VIII, IX, X, and XII, among others. When patients have conditions that necessitate the replacement of these clotting factors, fresh frozen plasma can effectively restore the blood's ability to coagulate.

While other components like fibrinogen and prothrombin are indeed present in fresh frozen plasma, the term "coagulation factors" encompasses a broader spectrum, which includes all the necessary proteins involved in the clotting cascade. This makes the answer particularly encompassing and accurate, as it identifies the complete range of vital proteins provided by fresh frozen plasma.

The other options, while relevant components of plasma, do not represent the entirety of what fresh frozen plasma offers in terms of coagulation support.
