Analyze the question: The question asks for the title of the administrative head of a public corporation (a government-owned enterprise like NNPC, NEPA/PHCN, or Nigerian Railway Corporation).

Explain the concept: Public corporations are set up by an Act of the legislature to run commercial or service activities for the government. They have a structure that differs from ministries:

• Ministries are headed politically by a Minister (or Commissioner at state level), while the Permanent Secretary is the administrative and accounting head (a civil servant).
• Extra-ministerial departments are headed by a Director-General.
• Public corporations are governed by a Board of Directors headed by a Chairman, while day-to-day administration is run by a General Manager (or Managing Director / Chief Executive).

Step by step elimination:

• A. Director General: usually heads extra-ministerial departments or some agencies, not the standard textbook answer for public corporations.
• B. General Manager: the chief executive and administrative head who manages daily operations of the corporation. ✔
• C. Head of Department: heads a unit within a ministry or organization.
• D. Minister: political head of a ministry.
• E. Permanent Secretary: administrative head of a ministry.

Answer: The administrative head of a public corporation is the General Manager, which is option B.

Tip: Remember the pairing:

• Ministry → Minister (political) / Permanent Secretary (administrative)
• Extra-ministerial department → Director-General
• Public corporation → Board Chairman (policy) / General Manager (administrative)
