Concept:Public corporations operate under the overall policy direction of the government through a supervising political authority.
Explanation:Statutory corporations are established by the government and are expected to implement its policies.
The minister, as the political head of a ministry, oversees these corporations and gives general policy guidelines.
The minister's direction guides the board of the corporation in forming its programmes.
The Board of Directors and Chairman manage day-to-day operations but do not set external policy.
The Permanent Secretary handles routine administrative work, not policy guidelines for boards.
Thus, the power to give policy guidelines to a board of corporations rests with the minister.
Answer:Option B. Minister.
