A how far you can see with a telescope or binoculars
B how far you can see with the "naked eye"
C how well you can identify an object at night
D the distance in miles at which prominent objects are identifiable
AI Explanation

The correct answer is D) the distance in miles at which prominent objects are identifiable. In the context of a weather report, the term "visibility" refers to the maximum distance at which prominent objects can be clearly seen and identified. This is a key factor for safe navigation, as it indicates how far a mariner can see and discern features of the surrounding environment. The other answer choices do not accurately capture the meaning of visibility as used in weather reporting.
