Question 1483Navigation General

The correct answer is A) Vega + 0.1. The magnitude of a star indicates its brightness, with lower numbers representing brighter stars. Vega, with a magnitude of +0.1, is the brightest of the three stars listed. Altair has a magnitude of +0.9, which is less bright than Vega, and Antares has a magnitude of +1.2, which is the least bright of the three. Therefore, Vega is the brightest star based on the given magnitude information. The other options are incorrect because they do not represent the star with the lowest, and therefore brightest, magnitude value.
