To determine the outer limit of the exclusive economic zone (EEZ):
1. Under the United Nations Convention on the Law of the Sea (UNCLOS), the EEZ extends up to 200 nautical miles from the baseline of a coastal state.
2. This zone grants the coastal state rights to explore and exploit marine resources.
3. The other options (12, 24, and 36 nautical miles) refer to territorial waters or contiguous zones, not the EEZ.
Therefore, the correct answer is (3) 200 nautical miles from the baseline.
