Explanation:

Statement 1 is correct: The United Nations Convention on the Law of the Sea (UNCLOS) is an international treaty which was adopted and signed in 1982. It replaced the four Geneva Conventions of April, 1958, which respectively concerned the territorial sea and the contiguous zone, the continental shelf, the high seas, fishing and conservation of living resources on the high seas. The Convention has created three new institutions on the international scene : – the International Tribunal for the Law of the Sea, – the International Seabed Authority, – the Commission on the Limits of the Continental Shelf. Statement 2 is correct: UNCLOS provides two specific regimes which are fundamental to maritime security and order on the seas: the regime of consecutive maritime zones, and the jurisdictional trinity of flag, coastal and port state control. In fact, UNCLOS is the only international convention which stipulates a framework for state jurisdiction in maritime spaces. Statement 3 is correct: UNCLOS sections the oceans, splitting marine areas into five main zones, each with a different legal status: Internal Waters, Territorial Sea, Contiguous Zone, Exclusive Economic Zone (EEZ) and the High Seas. It provides the backbone for offshore governance by coastal states and those navigating the oceans. It not only zones coastal states’ offshore areas but provides specific guidance for states’ rights and responsibilities in the five concentric zones.
