A Hydrography
B Regulatory boundaries
C Ferry routes
D All of the above
AI Explanation

The correct answer is D) All of the above. According to the International Maritime Organization (IMO) and International Hydrographic Organization (IHO) standards, an Electronic Chart Display and Information System (ECDIS) must display the following information: 1) Hydrography - This includes water depths, bottom contours, and other seafloor features. 2) Regulatory boundaries - This includes things like maritime borders, shipping lanes, and other regulated areas. 3) Ferry routes - As part of the full navigational and geographical data required to be displayed. The ECDIS must provide this comprehensive set of information to the mariner, as required by the relevant international standards. The other answer choices are incorrect because they do not cover the full scope of data that must be displayed.
