Interactions among galaxies also are thought to influence a galaxy's type in at least some cases.Which of the following does not support the idea that interactions can shape galaxies?
A)the fact that more distant galaxies have larger redshifts
B)computer modeling of collisions between galaxies
C)the fact that galaxies with distorted appearances are more common at great distances than nearby
D)the presence of features such as "tails" extending out of galaxies,bridges between galaxies,and rings of stars around galaxies

The fact that more distant galaxies have larger redshifts is not relevant to the idea that interactions can shape galaxies. Redshift is a result of the expansion of the universe, and does not necessarily relate to galaxy interactions. The other options all support the idea that interactions can shape galaxies. Computer modeling and observations of distorted appearances, features such as "tails," bridges, and rings are all evidence of interactions between galaxies shaping their appearance.
