The tenure of the president of the UN Security Council is

1. Analyze the question The question asks how long the president of the UN Security Council stays in office.

2. Explain the concept The UN Security Council has 15 members: 5 permanent (USA, UK, France, Russia, China) and 10 non-permanent members elected for two-year terms. The presidency is not a long-term position. It rotates every month among the members, following the English alphabetical order of the members' country names.

3. Solution

• Each member takes the presidency in turn, in alphabetical order.
• Each presidency lasts one calendar month.
• So a country holds the presidency for just one month before the next member in the alphabet takes over.

Checking the other options:

• B (six months): Wrong. No Council role rotates on this schedule.
• C (two years): This is the term of a non-permanent member, not of the president.
• D (one year): Wrong. The presidency does not last this long.

4. Answer The tenure of the president of the UN Security Council is one month, which is option A.

5. Tip Remember: "Council = Circulates monthly." Do not confuse the two-year term of non-permanent membership with the one-month term of the presidency. JAMB likes to test this difference.
