When navigating in high latitudes and using a chart based on a Lambert conformal projection, __________.

Correct Answer: Option B — a straight line drawn on the chart approximates a great circle

Lambert conformal projections are conic projections where meridians converge. On these charts, a straight line represents a close approximation of a great circle track, which is the shortest distance between two points on the earth's surface, making it ideal for high-latitude navigation as described in Bowditch.
