B Correct answer
Explanation

S.J. Singer and G.L. Nicolson proposed the Fluid Mosaic Model in 1972. It describes the membrane as a fluid bilayer of phospholipids with proteins embedded like mosaic tiles. The phospholipids can move laterally, giving flexibility. Robertson proposed the earlier 'unit membrane' model. Knoll and Ruska were electron microscopy pioneers.
