Solution
The correct option is B 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.
- 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'.
