- BA line along which the vessel is known to lie at a given moment based on a single observation✓ correct
- CThe vessel's dead reckoning track advanced to a new time
- DA bearing to a single object that has been doubled to determine distance off
Why B is correct
Bowditch Ch. 7 §701 defines an LOP as a line along which the vessel is known to lie at a given moment based on a single observation. The intersection of two or more simultaneous LOPs constitutes a fix, not a single LOP.
