Answer 1

B- the cell membrane

Step-by-step explanation:

Cell membranes are made up of lipids, proteins and cholesterol. These make up a selectively permeable layer that only allows for the movement of few molecules across the cell surface.

The lipid layer only allows for the passage of small non-polar molecules, while larger molecules require transport proteins to ferry other substances into the cell.
