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 ultimately about much more than a king's marital woes. Henry's actions led to England breaking away from the Roman Catholic Church, establishing the Church of England with himself as its head. This rejection of papal authority and establishment of a separate national church were the defining acts of the Reformation, reverberating throughout Europe and shaping the religious landscape for centuries to come.
