Which christian church did not allow their clergy to marry, believed that the pope had authority, and believed that the emperor ruled over the church?

The Catholic church  did not allow their clergy to marry, believed that the pope had authority, and believed that the emperor ruled over the church.

Catholics believe that the Pope, based in Rome, is the successor to Saint Peter whom Christ appointed as the first head of His church. Furthermore, the belief that religious figures should be celibate and cannot marry began long before the birth of Christianity.

this question makes no sense dude

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )
