Which structure is an example of a phospholipid bilayer?

A) DNA

B) Ribosomes

C) Inner membrane

D) Intermembrane space

I believe that this would be the inner membrane, or C. This is because the phospholipid layer is between the outer layers in the membrane, greatly restricting access inside and outside of the cell.

I believe the Intermembrane space is a type of phospholipid bilayer because the main function of it is oxidative phosphorylation.
