The Andromeda Galaxy shows a slight blueshift because **it is moving towards Earth and will collide with the Milky Way Galaxy.**
This is the correct answer because the gravitational interaction between the two galaxies is causing them to move closer to each other, and they are expected to eventually merge in approximately 4.5 billion years.
