Solution

The correct option is B Lipid enables lateral movement of proteins within the overall bilayer
According to the fluid mosaic model proposed by Singer and Nicolson (1972), the quasi-fluid nature of lipids enables the lateral movement of proteins within the overall bilayer. this ability to move within the membrane layer is measured as Fluidity.
So, the correct answer to the question is 'Lipid enables lateral movement of proteins within the overall bilayer'.
