Official USCG Answer & Rule Citation

Correct Answer: Option D — perigee

Per Bowditch, perigee defines the point in the Moon's elliptical orbit where it is closest to the Earth. Conversely, apogee represents the farthest point. Understanding perigee is critical for maritime navigation due to its direct influence on horizontal parallax and extreme tidal ranges.
