Correct option is (a) 2200-2500 RPM

For explanation I would say: Do not centrifuge immediately after drawing blood. Allow the blood to clot in an upright position for at least 30 minutes but not longer than 1 hour before centrifugation. Perform venipuncture as with any other blood collection device. Centrifuge for at least 15 minutes at 2200-2500 RPM within one hour of collection.
