C. Two magnets are pulled toward each other and stick together.

Explanation:

Two magnets pulled towards each other and sticking together best describes the role in which gravity plays in the formation of a galaxies.

A galaxy is a constellation of stars formed from a vast dense interstellar cloud of dust particles.

Gravity is a force of attraction between two bodies. The mass of one pulls on the other causes them to come together.

During the formation of galaxies, the interstellar clouds begins to aggregate and pull by the force of gravity. This then causes the dust to collapse leading to series of steps that degenerates into the formation of a galaxy from protostars.

We see that the magnetic force described is a force of attraction that pulls. Gravity is also a force of attraction that pulls bodies with masses.
