What happened as a result of the Great Schism of 1054?

I think the answer it’s A because I did some research and it said this “The Great Schism split the main faction of Christianity into two divisions, Roman Catholic and Eastern Orthodox. Today, they remain the two largest denominations of Christianity. On July 16, 1054, Patriarch of Constantinople Michael Cerularius was excommunicated from the Christian church based in Rome, Italy.”
