A Correct answer
Explanation

A star's color directly indicates its surface temperature through blackbody radiation. Hotter stars appear blue/white (surface temperatures above 10,000K), moderately hot stars appear yellow (like our Sun at ~5,800K), and cooler stars appear red (below 3,500K). This relationship is described by Wien's displacement law.
