The MOON TREATY 1979 (Agreement Governing the Activities of States on the Moon and Other Celestial Bodies) declares celestial bodies and their resources to be:

1. Article 11(1) Moon Treaty 1979: 'The moon and its natural resources are the common heritage of mankind.' 2. Article 11(5): States Parties undertake to establish an international regime to govern the exploitation of the natural resources of the moon as such exploitation is about to become feasible. 3. The Treaty has very FEW signatories — none of the major space-faring nations (USA, Russia, China, India) is a party. 4. The Outer Space Treaty 1967 (more widely accepted) prohibits military bases on celestial bodies but does NOT declare resources to be common heritage. 5. The 2020 ARTEMIS ACCORDS (USA-led) take a different approach permitting commercial extraction of space resources. 6. Hence option B is correct. _Source: UN Charter 1945 / Vienna Convention on Law of Treaties 1969 / Geneva Conventions 1949 / ICJ Statute / UDHR ICCPR ICESCR — Moon Treaty 1979, Article 11_
