The correct answer is C) Centrifugation.
Centrifugation is a separation technique used to separate particles from a liquid solution by spinning the solution at high speed in a centrifuge. Denser components move away from the axis of rotation, while lighter components move towards the axis. In diagnostic laboratories, centrifugation is routinely used for blood tests to separate blood components like plasma, red blood cells, white blood cells, and platelets, enabling various analyses on these different fractions.
