When neurons release their neurotransmitters, they release them by secretory vesicles fusing with the plasma membrane thereby emptying their contents into an area that can stimulate some response. What type of cellular transport is occurring as the vesicle forms and then surfaces on the cell's plasma membrane?

B) diffusion
C) exocytosis
D) pinocytosis
E) osmosis
