Public corporations are entities created by the state. They are government-owned enterprises established through an act of parliament, a decree, or an executive order to provide essential services to the public. Examples include the Nigerian National Petroleum Corporation (NNPC), the Nigerian Ports Authority (NPA), and the Power Holding Company of Nigeria (PHCN).
Key characteristics of public corporations include: they are owned by the government, they are established by law (statute or decree), they have a separate legal identity from the government, they are managed by a board of directors appointed by the government, and they are funded primarily from public revenue, though they may also generate their own income.
The other options are inaccurate. "Set up for production of goods" is too narrow - public corporations provide both goods and services (such as electricity, water, and transportation). "Created by an edict" is partially correct (some were created by military decrees), but this is not the defining characteristic and is too restrictive - many public corporations are created by acts of parliament. "Established by public/private partnership" describes a different arrangement - public-private partnerships involve shared ownership and management between government and private entities, which is distinct from a public corporation that is wholly state-owned.
