Which navigational risk increased for 18th-century ships after imperfect celestial observations led to cumulative positioning offsets?

A)Errors caused by parallax increased

B)Risk of grounding on uncharted coastlines✓

C)Magnetic compass drift became severe

D)Freshwater supplies were contaminated faster

💡 Explanation

Increased risk of grounding on uncharted coastlines results when celestial navigation yields an erroneous cumulative position estimate through systematic measurement offsets, because dead reckoning then places the ship at an incorrect location, thereby leading to unexpected landfalls, rather than correct courses.
