Answer: A. It contributed to the East-West Schism of 1054
Step-by-step explanation:
The Iconoclast Controversy was a period in the history of the Church where there were disagreements between people who believed that the church should not use religious images or icons as this amounted to idolatry and those who believed that using it would spread Christianity.
The Western Roman Church(Catholic) supported the use of religious images and icons while the Byzantine Church followed the decree of the Byzantine emperor in discarding religious images.
This contributed to the East-West Schism of 1054 where the Byzantines and western Roman church formally split by excommunicating each other.
