Concept:The United Nations Organization (UNO) works to maintain international peace and to encourage cooperation among nations.
Explanation:The UNO was established with several objectives stated in its Charter.
One of its main purposes is to achieve international cooperation in promoting and encouraging respect for human rights and fundamental freedoms for all people.
This objective is clearly mentioned in Article 1 of the UN Charter.
The UN pursues this through agencies such as the Human Rights Council and through various treaties and conventions.
Option A is incorrect because the UN does not have a standing army; it relies on peacekeeping forces contributed by member states.
Option B is incorrect because giving loans is mainly the role of the World Bank and the IMF, not the UNO.
Option D is incorrect because ensuring respect for African leaders is not an objective of the UNO.
Therefore, the correct objective is to promote and encourage respect for human rights and freedoms.
