Why are the star clusters in the tidal tail blue?

A: They are sad at being left behind. B: Blue stars in these newly active star-forming regions far outshine the less massive red stars. C: Blue stars are more massive and therefore have greater inertia, so they stay in place while the rest of the galaxy keeps moving. D: Blue stars are less massive and are therefore pulled away by tidal forces more easily. E: The individual stars were red before the interaction, and an injection of new matter onto them turned them blue.
