- A. The vessel's confirmed position at a given moment based on two observations
- B. The DR track projected forward from the last known fix
- C. The intersection of two or more simultaneous bearings to charted objects
- ✓ A line along which the vessel is known to lie based on a single observationCorrect
Why D is correct
A single observation produces a line along which the vessel is known to lie — that is the definition of an LOP. Two or more simultaneous LOPs are required to produce a fix. (Bowditch Ch. 7 §701)
