If one object has a large redshift and another object has a small redshift, what can we conclude about these two objects?
A) The one with the large redshift is moving toward us faster than the one with the small redshift. B) The one with the large redshift is moving away from us, and the one with the small redshift is moving toward us. C) The one with the large redshift is moving away from us faster than the one with the small redshift. D) The one with the large redshift is hotter and therefore is putting out more radiation. E) The one with the large redshift is redder than the other one.
