1. The PERSISTENT OBJECTOR rule: a State that has clearly and consistently objected to a rule of customary international law during the period of the rule's formation is NOT BOUND by that rule. 2. Recognized in Anglo-Norwegian Fisheries Case (UK v Norway), 1951 ICJ Rep 116 — Norway was not bound by the 10-mile bay rule because of consistent objection. 3.

Hence option B is correct. _Source: UN Charter 1945 / Vienna Convention on Law of Treaties 1969 / ICJ Statute / ARSIWA 2001 — Persistent Objector Doctrine; Anglo-Norwegian Fisheries Case (1951); ILC Conclusion 15 (2018)_
