   A team is testing an adaptive cruise control (ACC) system. The system is ASIL D, and the software is written in C. The team has a HIL system with the actual radar sensor and brake actuator. They need to verify the system's behavior in a critical cut-in scenario, which is dangerous to test on the road. They also need to ensure the code is free of dangerous pointer arithmetic. Which combination of techniques is most appropriate?

   • AHIL testing for the cut-in scenario and static analysis for pointer arithmetic
   • BMIL testing for the cut-in scenario and MC/DC for pointer arithmetic
   • CSIL testing for the cut-in scenario and code review for pointer arithmetic
   • DBack-to-back testing for the cut-in scenario and exploratory testing for pointer arithmetic

   A team is testing a lane-keeping assist (LKA) system. The system is ASIL C, and the software is written in C. The team has a HIL system with the actual camera and steering actuator. They need to verify the system's behavior under various lighting conditions, which are difficult to reproduce in a lab. They also need to ensure the code is free of runtime errors like division by zero. Which combination of techniques is most appropriate?

   • AMIL testing with a simulated camera and MC/DC for runtime errors
   • BHIL testing with a real camera and code review for runtime errors
   • CSIL testing with a simulated camera for lighting conditions and static analysis for runtime errors
   • DBack-to-back testing and exploratory testing for runtime errors

   A team is testing a battery management system (BMS) for an electric vehicle. The system is ASIL D, and the software is developed using a model-based approach. The team has a high-fidelity plant model of the battery and the control software model. They need to verify the software's behavior under extreme temperature conditions that are difficult to reproduce on a HIL system. Which test technique is most appropriate?

   • ASoftware-in-the-loop (SIL) testing with the plant model
   • BManual code review of the generated C code
   • CStatic analysis on the plant model
   • DHardware-in-the-loop (HIL) testing with a real battery
