Under Article 92 UN Charter, the principal JUDICIAL ORGAN of the UN is:

1. Article 92 UN Charter: 'The International Court of Justice shall be the principal judicial organ of the United Nations. It shall function in accordance with the annexed Statute, which is based upon the Statute of the Permanent Court of International Justice and forms an integral part of the present Charter.' 2. The ICJ replaced the Permanent Court of International Justice (PCIJ) of the League of Nations. 3. The ICC (International Criminal Court) is a separate treaty-based body created by the Rome Statute 1998; it is NOT a UN organ. 4. The Permanent Court of Arbitration (PCA) is a separate inter-governmental body created by the 1899 Hague Convention. 5. Hence option B is correct. _Source: UN Charter 1945 / Vienna Convention on Law of Treaties 1969 / ICJ Statute / ARSIWA 2001 — UN Charter 1945, Article 92_
