   An autonomous vehicle company is developing a system that must navigate in both urban and highway environments. In urban areas, the system must detect pedestrians and cyclists; on highways, it must predict the behavior of other vehicles at high speed. The company has limited computational resources on the vehicle and must prioritize real-time decision-making. Which approach best balances perception accuracy and computational efficiency?

   • AUse collaborative filtering to predict traffic patterns based on other drivers' routes
   • BUse a multi-modal sensor fusion system with object detection for urban obstacles and dedicated highway-speed prediction models, optimized to run on the vehicle's onboard hardware
   • CUse a single large deep learning model that handles all perception and decision-making, running in the cloud
   • DUse neural machine translation to interpret traffic signs and query understanding to rank possible routes
