The correct answer is D) 1, 2 and 3.
All three statements are correct according to the United Nations Convention on the Law of the Sea (UNCLOS).
Statement 1 is correct. Article 3 of UNCLOS states that every State has the right to establish the breadth of its territorial sea up to a limit not exceeding 12 nautical miles, measured from baselines determined in accordance with the Convention.
Statement 2 is correct. Article 17 of UNCLOS grants ships of all States, whether coastal or land-locked, the right of innocent passage through the territorial sea. Innocent passage means navigation through the territorial sea that is not prejudicial to the peace, good order, or security of the coastal State.
Statement 3 is correct. Article 57 of UNCLOS states that the Exclusive Economic Zone (EEZ) shall not extend beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured.
UNCLOS is a comprehensive treaty governing the uses of the oceans and their resources. It establishes different maritime zones (internal waters, territorial sea, contiguous zone, exclusive economic zone, continental shelf, high seas, and the Area) and defines the rights and obligations of states within each zone.
