Which cellular process is responsible for the release of wastes or cell products from inside to outside a cell?

Recall the definition of Exocytosis: Exocytosis is the process where vesicles containing waste or cell products fuse with the plasma membrane, releasing their contents outside the cell.

Compare the options: Endocytosis, Pinocytosis, and Phagocytosis involve bringing substances into the cell, which is the opposite of what the question asks. Exocytosis matches the description of releasing substances outside the cell.
