Which of the following is an example of a public sector enterprise?

A government-funded school is an example of a public sector enterprise because it is owned and operated by the government, funded through taxpayers' money, and its primary goal is to provide education to the community rather than to generate profit. Public sector enterprises like government-funded schools exist to meet the needs of the public and to provide essential services that may not be provided efficiently by the private sector, ensuring access to education for everyone.

In contrast, a private school operates independently of government funding and relies on tuition fees paid by students, making it a private enterprise. A non-profit organization may serve the public good but does not operate under the same mandate or funding principles as a public sector entity. A retail corporation, on the other hand, is a for-profit business focused on selling goods or services, and thus does not fall within the public sector either.
