The question asks precisely what a coastal State's sovereignty over its territorial sea extends to under international law.
Only the option that lists all three dimensions together, the waters, the seabed and subsoil, and the airspace, correctly reflects the full territorial sovereignty a coastal State holds.
So, the correct answer is territorial waters, the seabed and subsoil underlying such waters, and the air space above them.
This question tests familiarity with the sequence of articles in Part VII of UNCLOS dealing with the high seas.
Working through the sequence of Part VII articles shows that the prohibition on sovereignty claims is specifically located in Article 89, distinct from the scope, freedoms, and peaceful use provisions that surround it.
So, the correct answer is Article 89.
The question asks what specific duty Article 94(7) UNCLOS places on a flag State after a serious marine casualty involving its ship and injury to nationals of another State.
Article 94(7) is narrowly worded around the duty to hold a formal inquiry through qualified persons, which distinguishes it from the more general compliance and jurisdiction duties found elsewhere in the same article.
So, the correct answer is to cause an inquiry to be held by or before suitably qualified person(s) into such casualty or incident.
The question fills in a blank describing the special legal relationship territorial waters have with the coastal State, beyond simply being "territory".
The word that captures an automatic, non-optional attachment to the coastal land is "appurtenance", which is why territorial waters are described as such rather than in terms of liability, equitable interest, or trust.
So, the correct answer is Appurtenance.
This question is about correctly stating what the right of "hot pursuit" under Article 111 UNCLOS actually permits.
The doctrine of hot pursuit is specifically about extending a coastal State's enforcement jurisdiction from its own waters onto the high seas, and it stops the instant the vessel reaches any other State's territorial sea.
So, the correct answer is a vessel, if it has committed a violation of the laws of a foreign State while in that State's sovereign or territorial waters, may be pursued onto the high seas.
The question asks which Supreme Court judgment contains the observation that "sovereignty is not 'given', but it is only asserted".
Only the Republic of Italy judgment engages with the question of how a State's sovereignty over its contiguous zone and exclusive economic zone comes into being, which is where the quoted observation appears.
So, the correct answer is Republic of Italy through Ambassador v. Union of India, (2013) 4 SCC 721.
