The correct statement is: The stars at the center bulge are typically older than the stars in the arms.

In general, the stars in the bulge of a galaxy, such as the Milky Way, are older and tend to be of lower mass compared to the younger, hotter, and often more massive stars found in the spiral arms. The spiral arms are actively forming new stars, while the bulge contains older stars.
