Concept:The Judicial Service Commission recommends candidates for appointment to high judicial offices.
Explanation:The commission’s duty is to screen and suggest suitable persons for judicial appointments.
One of the highest judicial positions to be filled through this recommendation is the Chief Justice of Nigeria.
The commission does not recommend persons to join the National Judicial Council, because the council is a separate body that handles judicial appointments.
The President and the President of the Senate are political offices, not judicial posts, so they are outside the commission’s recommendation power.
Therefore, the post referred to in the question is that of the Chief Justice of Nigeria.
Answer:D. Chief Justice of Nigeria
