70% to pass

Defense plans may cause the operation of electronic aids to navigation to be suspended with _______________.

A one day's notice
B a week's notice
C thirty (30
D D
AI Explanation

The correct answer is C) thirty (30) days' notice. The US Coast Guard regulations state that defense plans may cause the operation of electronic aids to navigation to be suspended with thirty (30) days' notice. This is to ensure adequate time for mariners to be informed of the changes and make necessary adjustments to their navigation plans. The other options are incorrect because one day's notice (A) or a week's notice (B) would not provide sufficient time for mariners to safely adjust to the changes, while option D is not a complete answer.
