Under Article 102 UN Charter, every treaty and international agreement entered into by any UN Member shall be:

1. Article 102(1) UN Charter: 'Every treaty and every international agreement entered into by any Member of the United Nations after the present Charter comes into force shall as soon as possible be registered with the Secretariat and published by it.' 2. Article 102(2): 'No party to any such treaty or international agreement which has not been registered in accordance with the provisions of paragraph 1 of this Article may invoke that treaty or agreement before any organ of the United Nations.' 3. This continues the League of Nations practice of registering treaties to combat secret diplomacy. 4. Registered treaties are published in the United Nations Treaty Series (UNTS). 5. Hence option B is correct. _Source: UN Charter 1945 / Vienna Convention on Law of Treaties 1969 / Geneva Conventions 1949 / ICJ Statute / UDHR ICCPR ICESCR — UN Charter 1945, Article 102_
