Final Answer

Thrombocytopenia is due to a deficiency of platelets.

Explanation

Thrombocytopenia refers to a condition characterized by an abnormally low number of platelets (thrombocytes) in the blood. Platelets are crucial for blood clotting and play a significant role in hemostasis—the process that prevents and stops bleeding. When platelet counts drop below normal levels, individuals may experience excessive bleeding, easy bruising, or prolonged bleeding from cuts.

The other options can be clarified as follows: Vitamin K is important for the synthesis of clotting factors but is not directly related to platelet count; leukocytes (white blood cells) are part of the immune system and do not play a role in clotting; factor VII is a type of clotting factor, but its deficiency leads to a different bleeding disorder known as hemophilia. Therefore, the correct answer in the context of thrombocytopenia is indeed a deficiency of platelets.
