The most common pathway taken by a newly synthesized protein that will be secreted by a cell is rough ER → Golgi → transport vesicle → plasma membrane. The rough ER is involved in protein synthesis and folding, while the Golgi apparatus modifies, sorts, and packages proteins. The transport vesicles then carry the packaged proteins to the plasma membrane for secretion. Choice C is the only option that follows this pathway.
