If the fatty acids of the cell membrane were completely saturated, a cell would be more permeable. Thus, the correct option is B.
What is a cell membrane?
A cell membrane may be defined as a biological membrane that untangles the interior of all cells from the external environment and shields the cell from its environment.
The presence of saturated fatty acids increases the membrane permeability due to the presence of only single bonds. It increases the transport of molecules between the inner and outer compartments of the cell.
Therefore, the correct option for this question is B.
