**Core Concept**
Cryoprecipitate is a blood product derived from plasma that is rich in clotting factors, particularly fibrinogen, factor VIII, and von Willebrand factor. It is used to treat bleeding disorders, such as hemophilia A and von Willebrand disease. Cryoprecipitate is formed when plasma is thawed and then cooled, causing the clotting factors to precipitate out of solution.

**Why the Correct Answer is Right**
Cryoprecipitate contains fibrinogen, which is essential for clot formation, as well as factor VIII and von Willebrand factor, which are crucial for the intrinsic pathway of coagulation. The correct answer is one of the components that is not typically found in cryoprecipitate.

**Why Each Wrong Option is Incorrect**
* **Option A:** Fibrinogen is a key component of cryoprecipitate, so this option is incorrect.
* **Option B:** Factor VIII is also present in cryoprecipitate, making this option incorrect.
* **Option C:** Von Willebrand factor is another essential component of cryoprecipitate, so this option is incorrect.

**Clinical Pearl / High-Yield Fact**
Cryoprecipitate is often used to treat patients with acquired coagulopathy, such as those with liver disease or severe trauma. It is also used to support patients undergoing cardiac surgery.

**Correct Answer:** D.
