You take a bearing of 191° and 313° to two objects. Which bearing of a third object will give the best fix?

Correct Answer: Option D — 249°

Bowditch principles for a three-object fix state that the lines of position should ideally intersect at equal angles around the compass to minimize geometric dilution of precision. A bearing of 249 degrees provides the most balanced angular spread relative to 191 and 313 degrees.
