When galaxies collide, the most relevant event that can happen is galaxies merge. While the gravitational interactions can disrupt their structures, most of the stars within the galaxies have a large amount of space between them, so they typically do not "destroy" each other. Galaxies can also change in size, but they do not necessarily triple in size uniformly. The idea of galaxies disappearing is not accurate; they may become part of a larger merged galaxy, but they do not simply vanish. So, the correct answer is galaxies merge.
