Solution

The correct option is B Ultracentrifugation.
B. Ultracentrifugation
Solution : Proteins inside a cell can be separated based on their weight and sedimentation rate during centrifugation at very high speeds. They sediment at the bottom of the homogenate solution that is centrifuged based on their molecular weight.
So the correct answer is "Ultracentrifugation".
