70% to pass

Chart information details to be used in ECDIS should be the latest edition of information originated by a government-authorized hydrographic office and conform to the standards of (the) _______________.

A International Hydrographic Organization
B International Maritime Organization
C US Coast Guard
D NASA
AI Explanation

The correct answer is A) International Hydrographic Organization. The International Hydrographic Organization (IHO) is the international authority responsible for setting the standards for nautical charts and publications, including electronic charts used in ECDIS (Electronic Chart Display and Information System). The IHO standards ensure that the chart information is the latest, most accurate, and officially authorized data provided by government hydrographic offices. The other options are incorrect because the International Maritime Organization (IMO) sets broader maritime regulations, the US Coast Guard regulates US waters, and NASA is the US space agency not responsible for nautical chart standards.
