The correct option is D International Court of Justice
The International Court of Justice (ICJ) is the UN’s main judicial organ. Presiding over the ICJ, or “World Court”, are 15 judges, each from a different nation, elected by the General Assembly and Security Council. The Court settles legal disputes between nations only and not between individuals, in accordance with international law. If a country does not wish to take part in a proceeding it does not have to do so, unless required by special treaty provisions. Once a country accepts the Court's jurisdiction, it must comply with its decision.
