Once Ligand Molecules Bind to Receptors in Coated Pits of a Plasma

Once ligand molecules bind to receptors in coated pits of a plasma membrane, the next step of receptor-mediated endocytisis would be:

A) coating detaches from vesicle
B) coated vesicle forms by endocytosis
C) ligands separate from receptors, which are recycled
D) contents of secondary lysosome are digested and released into the cytosol
E) endosome fuses with primary lysosome, forming secondary lysosome
