    A) Polycythemia Vera

    Explanation:

    Erythrocytosis refers to a condition of the blood in which the count of the Red blood cell in the blood increases due to abnormal proliferation of the red blood cells.

    The main cause of the primary erythrocytosis is caused by a disease called polycythemia Vera in which the stem cell starts producing a large number of a red blood cell.

    The increased number of the red blood cell leads to the thickening of the blood which lowers the flow of the blood in the body and the formation of blood clots.

    Thus, Option-A is the correct answer.

    The correct option is A. Polycythemia Vera

    Explanation:

    Polycythemia vera is a myeloproliferative disorder of bone marrow hematopoietic cells that causes excessive production of all types of blood cells.

    Primary erythrocytosis occurs as a result of polycythemia vera, in this myeloproliferative disorder the bone marrow produces too many red blood cells along with excessive amounts of white blood cells and platelets. Bone marrow under normal conditions produces blood cells and contains the precursor cells of the three series: red blood cells, white blood cells or leukocytes and platelets or thrombocytes, this disorder is characterized by excessive or uncontrolled proliferation or growth of these cells. The increased production of red blood cells or erythrocytes is called erythrocytosis.
