Final Answer :
C
Explanation :
Hematocrit determination measures the proportion of blood volume that is occupied by red blood cells. This is typically assessed after centrifuging a blood sample, which separates the blood into layers, allowing for the measurement of the red blood cell volume relative to the total blood volume.
