The correct answer is option 3: The Secretary General of the United Nations is appointed by the General Assembly upon the recommendations of the Security Council.

Let`s break down each option for a better understanding:

Option 1 states that the Secretary General is appointed by the General Assembly. While the General Assembly does have a crucial role in the appointment process, they do so based on the recommendations of the Security Council. Therefore, option 1 is not the complete answer.

Option 2 suggests that the Secretary General is appointed from among the officers of the permanent secretariat of the United Nations on the principles of seniority and merit. However, this is not accurate as the appointment is not limited to the officers of the permanent secretariat. The Secretary General can come from any background.

Option 3 is the correct answer. The General Assembly does appoint the Secretary General, but it does so based on the recommendations of the Security Council. The Security Council plays a central role in the selection process by nominating a candidate, and then the General Assembly confirms the appointment.

Option 4 incorrectly states that the Secretary General is appointed solely by the Security Council. While the Security Council does play a significant role in the process, it needs the approval and confirmation of the General Assembly.
