To answer this question, you need to understand what hemophilia is and how it affects the body. Hemophilia is a genetic disorder that affects the ability of blood to clot. This means that individuals with hemophilia experience prolonged bleeding, even from minor injuries.
In the given options, the correct answer is: "prevents blood from clotting normally due to the body’s inability to form fibrin proteins." Hemophilia prevents blood from clotting normally, and this is due to the body's inability to form fibrin proteins, which are essential for the blood clotting process.
Therefore, selecting the option that states "prevents blood from clotting normally due to the body’s inability to form fibrin proteins" will give you the correct answer.
