What does an h-r diagram relate a star's temperature to? a. the amount of heat created by the star c. the type of star b. the elements the star contains d. the star's absolute magnitude

The correct answer is option d, that is, the star's absolute magnitude.

Explanation:

The Hertzsprung-Russell diagram or the H-R diagram also called the color-magnitude diagram. It demonstrates the association of the color of the stars (temperature) with the luminosity of the star or absolute magnitude. The stars apparent magnitude at a distance of ten Parsec from Earth is known as the absolute magnitude of the star.
