70% to pass

A Mercator chart is a _______________.

A simple conic projection
B rectangular projection
C polyconic projection
D cylindrical projection
AI Explanation

The correct answer is D) cylindrical projection. A Mercator chart is a type of map projection that uses a cylindrical projection to represent the curved surface of the Earth on a flat map. This projection maintains the shape of land masses and preserves the angles between directions, making it useful for navigation. The other options are incorrect because they do not accurately describe the Mercator projection, which is a cylindrical projection, not a simple conic, rectangular, or polyconic projection.
