It will merge with other galaxies.

Explanation: Galaxy growth in the Universe is largely hierarchical — small systems merge and accrete to form larger ones. Gravitational interactions, dynamical friction, and tidal forces cause galaxies to collide and merge, building up more massive galaxies (often creating ellipticals in the process). The other choices are incorrect or misleading: stars don't generally dim as a galaxy gains mass, galaxies don't "spin into" groups as a general rule, and an entire galaxy does not simply collapse under its own gravity.
