Question 1: How do you ensure proper grounding and shielding in an automotive electrical system to protect sensitive electronics?

Which action should you take?

Choose only one option

By following industry standards for grounding and using shielded cables in high-interference areas

By using unshielded cables for simplicity

By focusing only on cost and ignoring grounding needs

By ignoring electromagnetic shielding in favor of weight reduction
