Text A positions AI as a 'powerful tool that expands human creativity' and positively discusses the new possibilities through collaboration. On the other hand, Text B questions the 'authenticity' and 'originality' of AI-generated content and warns of the danger of devaluing human artists, i.e., a threat. Both texts share the recognition of AI's influence, but their evaluations are contrasted as 'potential' versus 'threat'. Therefore, the correct option most accurately summarizes the arguments of both texts.
