Who are the scientists that proposed the fluid mosaic model?

The diagram given below represents a fluid mosaic model of the plasma membrane. Match the components marked as $A, B, C, D$ and $E$ in the diagram below from the list $(i)$ to $(vii)$.
$(i)$ Sugar $(ii)$ Protein $(iii)$ Lipid bilayer $(iv)$ Integral protein $(v)$ Cytoplasm $(vi)$ Cell wall $(vii)$ External protein

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:
