What Was the Fundamental Cause of the Reformation?

The fundamental cause of the Reformation was B. break with Rome.

While King Henry VIII's desire to divorce Catherine of Aragon was a significant catalyst, the Reformation was a much larger movement. Henry's break with the Roman Catholic Church, driven by his pursuit of a male heir and his challenge to papal authority, paved the way for England to establish its own Church independent of Rome. This had far-reaching consequences, leading to religious and political upheaval across Europe.
