All of the following are examples of public corporation in Nigeria EXCEPT?

The correct answer is Zenith Bank Plc. A public corporation is a government-owned entity that operates as a business or provides a public service. In Nigeria, examples of public corporations include the Joint Admissions and Matriculation Board (JAMB), the Nigerian Steel Development Authority, and the Nigeria Railway Corporation. However, Zenith Bank Plc is not a public corporation in Nigeria, but a private bank that is owned by shareholders. While it is a highly respected financial institution in Nigeria, it is not owned or controlled by the Nigerian government, and therefore cannot be classified as a public corporation.
