Thrombocytopenia is the correct answer because it is a disorder that results from a deficiency of circulating platelets. Platelets are important in the process of forming blood clots to help stop bleeding. In thrombocytopenia, there are not enough platelets in the blood, leading to an increased risk of bleeding and easy bruising.

Hemophilia (Choice A) is a genetic disorder where the blood does not clot properly, usually due to a deficiency in specific clotting factors, not platelets.

Sickle cell anemia (Choice B) is an inherited red blood cell disorder where the red blood cells become rigid and sticky, causing them to be sickle-shaped and leading to various complications, but it is not directly related to platelet deficiency.

Von Willebrand's disease (Choice C) is a bleeding disorder caused by a deficiency or defect in von Willebrand factor, a protein that helps blood clot, but it is not specifically a disorder resulting from a deficiency of circulating platelets.
