A Correct answer
Explanation

Most of the cases receptor mediated endocytosis from plasma membrane involves clathrin-coated vesicles. Macromolecules bind to cell-surface receptors, accumulate in clathrin-coated pits and enter the cell as a receptor and ligand complexes in clathrin-coated vesicles. Clathrin consists of three copies each of heavy chain and light chain, forming a three-legged structure called a triskelion.
