Answer: D. thrombocytopenia
Step-by-step explanation:
Thrombocytopenia is a condition that is characterized by abnormally low levels of thrombocytes (platelets) in the liquid blood. The condition is either acquired or inherited. The thrombocyte count may go below 50,000 per microliter which is extremely low.
The patients with this condition generally show no symptoms. Some individuals may experience external bleeding like nosebleeds, and bleeding gums. Some may experience spontaneous bleeding under the skin.
