Final answer:
The evidence that supports Joan of Arc's strong religious faith is her decision to share her religious visions with French leaders.
Step-by-step explanation:
The piece of evidence that best supports the inference that Joan of Arc possessed strong religious faith is: 'After three years of what she was certain were religious visions, Joan of Arc decided that she needed to share them with French leaders who could implement the prophecies.' This evidence shows that Joan believed she had received religious revelations and felt compelled to spread her message to the French leaders. It indicates her strong conviction and faith in her visions.
