Which of the following justifies the existence of public enterprises

Public enterprises are established to provide essential services to the public that the private sector may not be able to provide. These enterprises are owned by the government and are expected to operate in the interest of the public, and not necessarily to make profits. Examples of public enterprises include public transport companies, power generation and distribution companies, and health care institutions. The existence of public enterprises is justified by the need to ensure that these essential services are available to all members of the society, regardless of their ability to pay, and to ensure that they are run efficiently and effectively for the benefit of the public.
