Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.

Star formation consumes dust and gas, so galaxies where stars are oldest typically consist of higher proportions of dust and gas than other galaxies.

Star formation and the presence of young stars is common across galaxies, regardless of the proportions of dust and gas present.

Star aging emits gas and dust, so galaxies with the youngest stars typically have the lowest proportions of dust and gas.

The correct response is:
Stars form from dust and gas, so galaxies with younger stars typically consist of higher proportions of dust and gas than other galaxies.
This statement reflects the relationship between star formation and the presence of dust and gas in a galaxy. Younger stars indicate recent star formation, which requires dust and gas, whereas older stars suggest that star formation has occurred in the past, leading to consumption of those materials.
