Recognition proteins are a type of glycoproteins present in the plasma membrane that allow one cell of the body to recognize the other body cells by making contact with recognition proteins of other cells. Receptors proteins allow cell-cell communication by receiving extracellular proteins.

These proteins are important for proper growth and development of the cell. Therefore the correct answer is D.  involves proteins in plasma membranes.
