What does the fluid mosaic model of the cell membrane $NOT$ contain?

Select the correct statements regarding cell membrane in eukaryotic cell.
$A$. Membrane of human $RBCs$ has approximately $52\%$ protein.
$B$. Major phospholipids are arranged in a bilayer.
$C$. Extensions of the plasma membrane into the cell form mesosomes.
$D$. Tails towards the inner part of lipids are hydrophobic and thus protected from aqueous medium.
$E$. Glycocalyx is present on the outer surface of the plasma membrane.
Choose the correct answer from the options given below:

Statement $X$: The cell membrane is the main structural component.
Statement $Y$: It is the site for electron transport and is a selectively permeable membrane.

$RNA$ is absent in

How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not,then how are these transported across the membrane?

The main structural component of the plasma membrane of various cellular organelles is:
