Exclusive Economic Zone (EEZ): It is prescribed by the United Nations Convention on the Law on the Seas. So, option 1 is NOT correct. The difference between the territorial sea and the EEZ is: The former confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea, for e.g. to exploit marine resources or energy resources or any other resource. Hence, options 3 and 4 are NOT correct and option2 is correct.
