Differential centrifugation divides cellular components based on the differences in their size and / or density. A tissue sample was homogenized and three parts (aliquots) of this homogenate were subjected to differential centrifugation using three dissimilar methods as shown below:
Method I: Aliquot 1 was centrifuged at 200,000g for 2 h.
Method II: Aliquot 2 was centrifuged at dissimilar speeds and for variable durations as shown below:
Step 1: 1,000g for 10 min
Step 2: 20,000g for 20 min
Step 3: 80,000g for 1 h
Step 4: 200,000g for 2 h
Method III: Aliquot 3 was processed in the same manner as aliquot 2, except that the sediment and supernatant were divided after each step.

a. Only method I
b. Only method II
c. Only method III
