what evidence is there suggesting ellipticals may form from the mergers of 2 or more spiral galaxies
two or more nuclei have been found in the cores of elliptical galaxies
giant globular clusters
galactic bridges linking ellipticals
large regions of star formation

Explanation:

Elliptical galaxies forming from spiral mergers would retain traces of multiple original galactic centers. Multiple nuclei in elliptical cores directly indicate past mergers of separate galaxies (like spirals). Other options: Giant Globular Clusters are not unique to merger origins; Galactic Bridges link interacting galaxies (not post-merger ellipticals); Ellipticals have little star formation, so large star-forming regions are irrelevant.

Answer:

A. Two or more nuclei have been found in the cores of elliptical galaxies
