You are on course 042°T. To check the course of your vessel you should observe a celestial body on which bearing?

Correct Answer: Option B — 132°

Per Bowditch celestial navigation methods, cross-track error and course drift are verified by observing a celestial body positioned perpendicularly (90 degrees offset) to the vessel's true course of 042°T, yielding an azimuth of 132°T.
