When galaxies collide, the most accurate response is that galaxies merge. During such events, galaxies can combine to form larger galaxies. The other options provided—galaxies triple in size, disappear, or destroy their stars—are not typical outcomes of galaxy collisions. Instead, while individual stars within the galaxies are mostly spaced apart and do not collide directly, the overall structures of the galaxies can change significantly, and interactions between stars can lead to new star formation or other phenomena.
