The first statement best describes the responses of religious and political leaders to Martin Luther:
"The Roman Catholic Church excommunicated Martin Luther, but the Diet of Worms supported his ideas for religious reform."
The Roman Catholic Church excommunicated Luther in response to his criticisms of Church practices, particularly the sale of indulgences. However, the Diet of Worms, where Luther was summoned to address his teachings, did not support him; rather, they condemned his views, despite his significant influence and the growing support for reform among various political leaders and segments of the populace.
Note: The statement you provided regarding the Diet of Worms supporting Luther is potentially misleading, as the diet ultimately condemned him. If you are looking for clarity, the more accurate summary is that the Church excommunicated him while some political leaders began to support his reforms, leading to increased tension during that period.
