The correct answer is Option A.
Ultracentrifugation involves the separation of colloidal particles from the impurities by centrifugal force.
The impure sol is taken in a tube and the tube is placed in an ultracentrifuge. The tube is rotated at high speeds.
On account of this, the colloidal particles settle down at the bottom of the tube and the impurities remain in the solution.
This solution is termed as centrifugate. The settled colloidal particles are removed from the tube and are mixed with an appropriate dispersing medium. Thus, the pure sol is obtained.

The ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s2). There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.

HEY USER IN THIS QUESTION WHEN WE ROTATE THE COLLOIDAL SUBSTANCE WITH THE HAI SPEED GENERATE TO A ROTATIONAL MOTION WHERE WE COME TO A V EQUALS TO OMEGA R SO IN THE QUESTION WHEN WE ROTATE THE THE SUBSTANCE IT GETS TO TO CONCENTRATE AT A CENTRIFUGAL FORCE WHERE DOES IT APPEAR THAT'S WHY IN THIS QUESTION WE JUST VERIFY BY THE PROCESS OF CENTRIPETAL FORCE
