Concept:The question tests the historical origin of Nigerian federal institutions and which ones were created by the 1979 Constitution.
Explanation:The National Universities Commission (NUC) was not created by the 1979 Nigerian Constitution.
It was established earlier, in 1962, by an Act of the Federal Government.
NUC regulates and supervises the development of university education in Nigeria.
The 1979 Constitution set up the Police Service Commission, the Federal Electoral Commission, and the National Population Commission.
Thus, NUC is the only body among the options that did not originate from that Constitution.
Answer:Option B: National Universities Commission.
