The correct response is: They dispute an opposing view.
Paragraphs 3–5 address the dissatisfaction that some customers feel toward AI customer service, particularly highlighting the limitations of chatbots in complex situations and the perceived lack of empathy. This contrasts with the earlier assertions about the advantages of AI, thereby providing a counterargument that enriches the discussion about the integration of AI in customer service. By acknowledging these concerns, the paragraphs contribute depth to the central idea that while AI can improve efficiency, it cannot entirely replace the human element in customer interactions.
