The correct option is B Danielli and Davson
First molecular models of plasma membrane were the Lamellar or Sandwich models. Danielli and Davson in 1935, proposed a sandwich model for plasma lemma according to which, in a plasmalemma, a double phospholipid layer is surrounded on either side by a layer of hydrated globular proteins like protein-lipid-lipid-protein.
