We expect the kinds of galaxies that we see at a redshift of z = 4 to be:
A) much like what we see today
B) smaller and much more irregular looking than today
C) smaller versions of what we see today
D) far more numerous but with fewer spiral galaxies
E) larger versions of what we see today

A redshift of z = 10 means that we are looking at galaxies as they were when the universe was only about 400 million years old. At this stage of the universe's history, galaxies were still in the process of forming and were generally smaller and more irregular in shape compared to the galaxies we see today. Therefore, option B is the best choice as it describes the expected appearance of galaxies at this redshift.
