Solution

The correct option is D Danielli and Davson
  • Davson and Danielli in the year 1935 proposed that the cell membranes are made up of lipid bilayers which are coated with thin sheets of protein (first lipid model of biomembranes)
  • This model of cell membranes has a lipid centre which is surrounded by single layers of lipid that are covered by single protein layers.
  • This theory is called pauci-molecular theory which illustrates that the cell membrane is a sandwich (protein-lipid-protein) which are applicable to all biological membranes.
  • So, the correct answer is 'Danielli and Davson'.
