Polycythemia is a result of?

Increased WBC
Decreased RBC
Increased RBC
Decreased WBC

The correct answer is: Increased RBC

Polycythemia is a medical condition in which there is an increased number of red blood cells in the blood. This can be caused by various factors such as genetic mutations, chronic hypoxia, and certain types of cancer. Option A and D, increased and decreased white blood cells respectively, are not related to polycythemia as it specifically refers to an increase in red blood cells. Option B, decreased red blood cells, is also incorrect as it is the opposite of what polycythemia signifies. Therefore, the correct answer is C, increased red blood cells.
