The correct answer is C) Name and miles from a reference point. On Army Corps of Engineers navigation maps, navigation lights are typically identified by their name and the distance in miles from a reference point, such as a river mile marker or a nearby landmark. This allows boaters to easily locate the light on the map and determine its position relative to their current location. The other answer choices are incorrect because they do not accurately reflect how navigation lights are depicted on Army Corps of Engineers maps. Option A) would be more typical of a Coast Guard chart, while option B) is not a standard way of identifying navigation lights on these maps.
