Which of the following best describes a fix in marine navigation?

- BA dead reckoning position advanced from a known point
- CThe intersection of two or more lines of position taken simultaneously✓ correct
- DAn estimated position derived from course and speed over time
Why C is correct
A fix is the intersection of two or more LOPs taken simultaneously. A single bearing produces only a line of position, not a fix. (Bowditch Ch. 7 §701)
