Final answer:
Elizabeth I was the only supreme governor of the state and maneuvered the religious tensions in England, promoting Protestantism within a framework that sought outward conformity. The true statement about Elizabeth I is option A.
Step-by-step explanation:
The true statement about Elizabeth I is that she became the only supreme governor of the state. Contrary to some perceptions of her rule, Elizabeth I was not extreme in her foreign policy, instead often maneuvering diplomatically while supporting English privateers against Spanish interests.
During her reign, she worked to balance the religious tensions between Protestantism and Catholicism in England, leaning towards Protestantism with the Church of England but requiring outward conformity to the state church rather than enforcing adherence to strict Protestant doctrines.
