A Correct answer
Explanation

In astronomy, the brightest star in a constellation is designated Alpha (first letter of Greek alphabet). This follows the Bayer designation system created by Johann Bayer in 1603, where stars are labeled with Greek letters in order of brightness within their constellation. For example, Alpha Centauri is the brightest star in the Centaurus constellation. Beta is second-brightest, followed by Gamma, then Delta.
