The question is incomplete as it does not have the figure which is attached
Answer:
C) stabilization of the phospholipids
Explanation:
The figure shows the diagrammatic representation of the plasma membrane of the cells.
In the given figure the Structure E which is represented by the orange color represents the cholesterol as it is presently integrated into the plasma membrane.
Cholesterol is a steroid which helps maintain the structure of phospholipids by attaching its OH group to the hydrophilic portion or polar head of the phospholipids and the no-polar chains to the non-polar structure of the phospholipids. This stabilizes the structure of the phospholipids.
Thus, Option-C is the correct answer.
