The `exec_()` function in PyQt5.Qt.QMenu is used to display the menu in the specified position and waits for the user to select an option. It performs a modal operation, which means that the program stops executing until the user either selects an option or dismisses the menu. Once the user selects an option, the function returns the selected QAction, allowing the program to perform the corresponding action.
