Nigerian Ports Authority is an example of

Step 1: Analyze the question The question asks what type of organisation the Nigerian Ports Authority (NPA) is.

Step 2: Explain the concepts

• Civil Service: The permanent, non-political staff of government ministries and departments (e.g., Federal Ministry of Education). It carries out government policies directly.
• Public Service: A broad term covering all government employees and institutions, including the civil service, the military, the police, the judiciary, and parastatals. It is the wider umbrella.
• Public Corporation: A business organisation set up by an Act of the National Assembly (or a law/decree), owned and financed by government, to provide essential services or run commercial activities in the public interest. Examples are the NPA, NNPC, NEPA (now under the power sector companies), and the Nigeria Airways (formerly).
• Maritime Corporation: Not a standard classification of organisations in Government studies.

Step 3: Apply to the question The NPA was established by an Act of the National Assembly (originally the Ports Act of 1954, with later amendments). It is government-owned and operates and manages Nigeria's seaports, which is a service the government provides. This matches the definition of a public corporation, also called a parastatal.

You could argue that the NPA is also part of the public service, since public corporations fall under it. However, the question asks for the specific type of organisation, and the most precise answer is Public Corporation. The civil service doesn't fit because the NPA is not a ministry or department. "Maritime Corporation" is not a recognised category.

Step 4: Answer The correct option is C. Public Corporation.

Tip: When you see an organisation name like NPA, NNPC, FRSC, or CBN, think "parastatal" or "public corporation": it is set up by law, owned by government, and serves the public. Pick the most specific option when a broader one (like Public Service) is also listed.
