the milky way will engulf the andromeda galaxy.
they will merge to create one super galaxy.
they will crash together and both explode.
the andromeda galaxy will engulf the milky way.

Explanation:

Astronomical research shows that the Andromeda galaxy and the Milky Way are on a collision course. When they meet, due to gravitational interactions, they will merge rather than one engulfing the other or both exploding. The result of this merger will be the formation of a single super galaxy.

Answer:

B. They will merge to create one super galaxy.
