Question 102Navigation Problems

The correct answer is B) Regulus, Canopus, Antares. Explanation: 1) The correct answer is B. This is because Regulus, Canopus, and Antares are bright, prominent stars that are well-suited for celestial navigation fixes at the given latitude and longitude. 2) The criteria for selecting the best stars for a fix include the stars' magnitude (brightness), azimuth (direction), and altitude (height above the horizon). Regulus, Canopus, and Antares meet these criteria - they are bright, visible in the southern hemisphere at the given coordinates, and will be at a good altitude for taking sights. 3) The other options are less suitable - Spica, Arcturus, and Alioth are more northern stars, while Avior, Sabik, and Fomalhaut may not be as prominent or favorably positioned for a fix at that location.
