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 traces of the original galaxies' cores. Multiple nuclei in elliptical cores directly indicate past mergers of galaxies (each with its own nucleus). Other options are not specific: large star formation is more linked to irregulars/interacting galaxies, giant globular clusters don’t signal mergers, and galactic bridges link interacting galaxies (not ellipticals’ formation from spirals).

Answer:

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