Correct option (c) differential centrifugation
Explanation:
Differential centrifugation is the mechanical separation of individual sub-cellular components from homogenate in centrifuge at low speed. depending upon the size, specific gravity, mass. density, different organelles are separated and settled at the bottom of the centrifuge tube at different centrifugal speeds.
Ultracentrifuges have 50,000-1,00,000 rpm and are used for the separation of minute cell organelles and constitutents on the basis of different densities.
