Who primarily administers organizations in the public sector?

The primary administration of organizations in the public sector is typically handled by national governments and local authorities. This is because the public sector is composed of agencies and organizations that are funded and operated by government entities to serve the public interest. National governments and local authorities have the responsibility of managing resources, creating policies, and providing essential services like healthcare, education, and public safety.

In contrast, private companies and individual entrepreneurs operate in the private sector, where the primary aim is profit generation rather than public service. Local charities, while they may provide valuable services, generally operate independently from government administrations and are not primarily responsible for the larger framework and governance of public sector organizations. Thus, the option regarding national governments and local authorities accurately reflects the entity types responsible for overseeing public sector bodies.
