Correct Option: A

Secretaries-General serve for five-year terms that can be renewed indefinitely, although none so far has held office for more than two terms. The United Nations Charter provides for the Secretary-General to be appointed by the General Assembly upon the recommendation of the Security Council, where the permanent members have veto power. The General Assembly can theoretically override the Security Council’s recommendation if a majority vote is not achieved, although this has not happened so far. There are no specific criteria for the post, but over the years, it has become accepted that the post shall be held for one or two terms of five years, that the post shall be appointed on the basis of geographical rotation, and that the Secretary-General shall not originate from one of the five permanent Security Council member states.
