   An automotive software team is developing a new infotainment system. The project is in the early design phase, and the team wants to identify potential defects in the software architecture before writing any code. The system is not safety-critical but has complex interactions with vehicle sensors. Which static test technique is most appropriate for this context?

   • ACode review of the existing legacy modules
   • BDynamic testing of the hardware-in-the-loop (HIL) setup
   • CArchitecture analysis using a formal notation like EAST-ADL
   • DData flow analysis on the compiled binary

   A team is testing a transmission control unit (TCU). The system is ASIL C, and the software is developed in Simulink. The team has a model of the TCU and the generated C code. They need to verify that the model and the code behave identically, and they also need to achieve a high level of structural coverage on the code. Which combination of techniques is most appropriate?

   • ABack-to-back testing between the model and the code, followed by MC/DC on the code
   • BSIL testing with the generated code and static analysis
   • CRequirements-based testing on the model and statement coverage on the code
   • DHIL testing with the real TCU and code review
