Which one of the following is not a United Nations entity?

While the International Red Cross and Red Crescent Movement is an important international humanitarian organization, it is not an entity directly affiliated with the United Nations. The ICRC operates independently and has its own distinct organizational structure and mandate. It is recognized globally for its efforts in providing humanitarian assistance and protecting the lives and dignity of those affected by armed conflicts and disasters. However, it is separate from the United Nations and maintains its own relationships with governments and other organizations.
