   A startup company is developing a new electric vehicle (EV) and wants to validate the battery management system (BMS) software. They have a limited budget and cannot afford multiple physical battery packs for testing. They have a detailed simulation model of the battery cells. What is the primary benefit of using SiL testing in this situation?

   • AIt allows testing to be performed only after the vehicle is built
   • BIt reduces the need for physical hardware, lowering testing costs
   • CIt guarantees the BMS software will be free of all defects
   • DIt eliminates the need for any other type of testing
