A few statements about centrifugation method are given:I. The mixture ...
Centrifugation is a method used to separate mixtures of substances based on their density differences. It involves rotating a mixture at a high speed in a centrifuge machine. Let's analyze each statement given and determine which ones are correct:

I. The mixture containing very small suspended particles is rotated at a high speed in a centrifuge machine.
This statement is correct. In centrifugation, the mixture is placed in a tube or container and subjected to high-speed rotation in a centrifuge machine. The high-speed rotation causes the denser particles to move towards the outer edges of the tube, while the lighter particles or liquid components remain towards the center.

II. The denser particles stay at the top.
This statement is incorrect. In centrifugation, the denser particles actually move towards the bottom, not the top. The centrifugal force generated by the high-speed rotation causes the denser particles to sediment towards the bottom of the tube, forming a pellet.

III. The method is used to separate water from wet clothes in a washing machine.
This statement is incorrect. Centrifugation is not used to separate water from wet clothes in a washing machine. Washing machines typically use a spin cycle to remove excess water from clothes by applying centrifugal force. However, this process is different from centrifugation as it aims to remove excess liquid, not separate different components of a mixture.

IV. The method can be used in laboratories for separating plasma and platelets.
This statement is correct. Centrifugation is commonly used in laboratories to separate plasma and platelets from blood samples. Blood is centrifuged at high speeds to separate its components based on their densities. The denser red blood cells settle at the bottom, while the plasma and platelets remain in the upper layer.

Based on the analysis of each statement, the correct statements are:
- I. The mixture containing very small suspended particles is rotated at a high speed in a centrifuge machine.
- III. The method is used to separate water from wet clothes in a washing machine.
- IV. The method can be used in laboratories for separating plasma and platelets.

Thus, the correct answer is option 'D'.
