Which of the following is a way to scale back bureaucracy by turning over bureaucratic functions to private entities?

The correct choice is privatization, which refers to the process of transferring ownership or management of a public service or function to private entities. This approach is often implemented with the goal of increasing efficiency, cutting costs, and reducing the size of government bureaucracy. By allowing private companies to take over certain government functions, it is believed that the competition and profit motive will lead to improved services and innovation, enabling a more streamlined and effective operation compared to traditional government-run programs.

The term "scaling" typically refers to adjusting the size or scale of an organization or system but does not specifically relate to the transfer of functions to the private sector. "Commerce" deals more broadly with the activities of buying and selling goods and services and doesn’t focus on the administrative aspect of government functions. "Economization" can refer to making something more economical or efficient but again does not specifically denote the transfer of responsibilities from the public to the private sector in the context of bureaucracy.
