• a majority of stars in most galaxies are red giants

• the light slows down as it nears Earth

• red light travels faster than other colors of light

In the diagram, the spectral lines of hydrogen gas from three galaxies, A, B, and C, are compared to the spectral lines of hydrogen gas observed in a laboratory. What is the best inference that can be made concerning the movement of galaxies A, B, and C.

• Galaxy A is moving away from Earth, but galaxies B and C are moving toward Earth

• Galaxy B is moving away from Earth, but galaxies A and C are moving toward Earth

• Galaxies A, B, and C are all moving toward the Earth

• Galaxies A, B, and C are all moving away from the Earth
