The lipids present in the bilipid layer of the plasma membrane can move between both the leaflets of the bilayer in a transverse manner or show a flip-flop movement.
Whereas, the proteins present in the bilipid layer proteins cannot move due to the extensive polar regions.
So, the correct answer is 'Lipids can rarely flip-flop, proteins cannot'.
