With reference to the United Nations Convention on the Law of Sea, consider the following statements : 1. A coastal state has the right to establish the breadth of its territorial sea up to a limit not exceeding 12 nautical miles, measured from baseline determined in accordance with the convention. 2. Ships of all states, whether coastal or land-locked, enjoy the right of innocent passage through the territorial sea. 3. The Exclusive Economic Zone shall not extend beyond 200 nautical miles from the baseline from which the breadth of the territorial sea is measured. Which of the statements given above are correct ?

States (India in this text) are described as extending territorial waters to a distance of 12 nautical miles measured from the appropriate baseline — a clear rule about breadth and baseline measurement.

A student could take this national practice as an example of an accepted international norm and compare it with UNCLOS text or other states' practice to judge whether 12 nm is the conventional upper limit.

A regulatory notification is said to cover '12 nautical miles in the sea', indicating administrative/regulatory recognition of a 12 nm zone seaward of baselines.

Use this as evidence that coastal regulation treats 12 nm as a distinct maritime band; a student could check international law instruments (or other coastal states' regulations) to see if 12 nm is the internationally referenced limit.

An independent school-level source repeats that territorial waters extend 12 nautical miles from the appropriate baseline — reinforcing the pattern across different texts.

Treat repeated national textbook statements as a pattern of state practice; then consult authoritative international sources (UNCLOS or summaries) to test whether 12 nm corresponds to the Convention's limit.
