The most likely pathway for a newly synthesized protein that will be secreted by a cell is through the secretory pathway, which involves transport from the endoplasmic reticulum (ER) to the Golgi apparatus, followed by packaging into vesicles that fuse with the plasma membrane for secretion outside the cell. This process is responsible for the secretion of many proteins, such as hormones and enzymes, and is the most efficient way for cells to deliver proteins to their target destinations. Therefore, choice C - ER → Golgi → vesicles that fuse with plasma membrane - is the best option.
