Final answer:
The correct answer is option c) His humility and dedication to the church.
Step-by-step explanation:
Evidence of profound conversion in Becket could be exemplified by his humility and dedication to the church. Initially, after Constantine's conversion, Christian bishops saw a dramatic increase in secular power, blending church hierarchy with Roman political systems. In the context of Henry VIII, he rejected the authority of the Catholic Church primarily because he was angry that the pope would not annul his marriage to Catherine of Aragon (Henry VIII's annulment crisis).
Conversion in Europe was also often politically motivated, as with Charlemagne, who facilitated the spread of Christianity amongst Germanic peoples to consolidate political relationships (political conversion). In the 11th century, Pope Gregory VII's stand against simony empowered the papacy over temporal rulers, shifting church appointments from kings to the pope.
Hence, Becket's transformation could also be seen against the backdrop of these historical church-state power dynamics, where bishops began to serve administrative roles to bolster their cities and congregations.
