a) constantine became the new ruler of the roman church
b) built it to resemble “old rome”
c) combined the western and eastern roman empires
d) discarded old roman traditions and began new ones

The correct answer is B. When Contantine rebuilt Byzantium, he modelled the city partly on 'Old Rome', and it was his intention that the new city would resemble the old one. 'New Rome' was a name that Roman Emperor Constantine the Great christened the city with himself.
