Final answer:

Step-by-step explanation:
The correct answer is 3) Edema. Edema is not a sign of hematologic disorders. Hematologic disorders are conditions that affect blood and blood-forming organs, such as the bone marrow, blood vessels, and the spleen. Signs of hematologic disorders include infarction, thrombosis, shock, and headache. Edema, on the other hand, is the abnormal accumulation of fluid in the tissues and is not specific to hematologic disorders.
