You are on course 226°T. In order to check the latitude of your vessel, you should observe a celestial body on which bearing?

Correct Answer: Option C — 000°

To determine latitude, a navigator should observe a celestial body on the celestial meridian, which is at a bearing of 000° or 180°. Observing a body at meridian passage provides the most accurate latitude calculation, as the body's altitude is at its maximum and its rate of change is minimal.
