Galaxy composition typically relate to the age of the stars in the galaxy
through Stars being able to form from dust and gas, so galaxies with
younger stars typically consist of higher proportions of dust and gas than
other galaxies.
<h3>Components of a Star</h3>
The age of stars are usually determined through the amount of gas and dust
present in them. Stars burn gas to emit light and the younger ones have
more proportion of gas present than the older ones. The older ones have
less proportions due to more gas being burned over time.
The stated facts therefore makes option C the most appropriate.
