Question

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

large regions of star formation

giant globular clusters

galactic bridges linking ellipticals

Explanation:

Elliptical galaxies formed by merging spirals would retain multiple nuclei from the original spiral cores. The other options are not direct evidence: large star formation regions are more typical of spirals, giant globular clusters do not indicate mergers, and galactic bridges link interacting galaxies (not merged ellipticals' origin).

Answer:

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