Which of the following statements regarding animal cell membrane is correct?

Animal cell membranes follow the fluid-mosaic model and are composed of a phospholipid bilayer with embedded and peripheral proteins, along with cholesterol molecules interspersed in the bilayer that regulate membrane fluidity. Carbohydrates also occur as glycoproteins/glycolipids on the outer surface. Therefore the most complete and correct description is that the animal cell membrane is composed of phospholipids, proteins and cholesterol (a lipid). The other options omit cholesterol, which is a characteristic and essential component of animal (not plant) cell membranes.
