Solution

The correct option is B
Proteins embedded in two layers of phospholipid

The most widely accepted model for plasma membrane structure is the fluid mosaic model. According to this model, the plasma membrane is made up of a phospholipid bilayer which has proteins embedded in it. These proteins can be extrinsic/external proteins or intrinsic/internal proteins.
