   A team is setting up a SiL test environment for an autonomous driving function. They need to simulate the vehicle's sensors (camera, radar, lidar) and the vehicle dynamics. Which set of components is essential for this SiL setup?

   • AReal sensors, real actuators, and a real-time simulator
   • BThe actual ECU hardware, a breakout box, and a power supply
   • CA vehicle on a test track, a data logger, and a driver
   • DPlant models for sensors and vehicle dynamics, the compiled software under test, and a host PC

   In a HiL test for an anti-lock braking system (ABS), the test results show that the wheel speed sensors report a constant value even when the simulated vehicle speed changes. The ABS does not activate. What is the most likely cause?

   • AThe plant model is too simple to simulate wheel speed
   • BThe ABS software has a bug that prevents activation in all conditions
   • CThe test case is not repeatable
   • DThe wheel speed sensor signals are not properly connected or configured in the HiL setup
