   An autonomous vehicle must navigate a city street. It needs to identify pedestrians, other vehicles, and traffic signs, and then decide whether to stop or proceed at an intersection. Which combination of AI capabilities is required?

   • ACollaborative filtering to recommend routes based on other drivers' choices and spam filtering to remove irrelevant sensor data
   • BObject detection to perceive the environment and path planning/decision-making to determine safe actions
   • CNeural machine translation to interpret traffic signs in multiple languages and query understanding to rank possible routes
   • DScene recognition to identify the type of road and adaptive difficulty to adjust driving speed

   A bank's customer service chatbot must handle routine balance inquiries and transaction history requests, but it must also detect potential fraud indicators in customer messages (e.g., 'I didn't make this purchase') and escalate those to a human agent immediately. The chatbot must not escalate routine inquiries, to avoid overloading human agents. Which design best meets these requirements?

   • AUse object detection to analyze the customer's profile picture and decide whether to escalate
   • BUse a single machine learning model trained to answer all queries, including fraud-related ones, without human escalation
   • CUse natural language understanding to classify intent, and a separate fraud-detection model that flags high-risk messages for escalation
   • DUse collaborative filtering to recommend responses based on similar customers' past conversations
