Best answer
Correct Answer - Option 3 : temperature

Concept:

  • Star: The celestial body which consists of a luminous sphere of plasma held together by its own gravitational field is called a star.
    • The Stars are classified by the spectrum and their temperature

Explanation:

  • The color of a star mostly indicates a star's temperature, and it can also suggest the star's age. So option 4 is correct.
  • Class O stars, which are blue in color, are the hottest, and class M stars, which are red in color, are the coldest.
