Question

Quizplus · Accepted Answer

Option A and D are incorrect because elliptical galaxies do not typically have blue stars or much gas and dust. Option B is also incorrect because red stars indicate older populations, and elliptical galaxies do not typically have large amounts of gas and dust.
