The correct answer emphasizes that type AC cable used in places of assembly must include an insulated equipment grounding conductor. This requirement is crucial for safety and compliance with electrical codes, as an insulated equipment grounding conductor provides a reliable pathway for fault currents, minimizing the risk of electrical shock and fire hazards.

In environments such as places of assembly, where the safety of the public is a priority, having an effective grounding system is essential. The insulated equipment grounding conductor effectively connects metal parts of the electrical system to the ground, ensuring that in the event of a fault, the circuit can be safely de-energized, protecting both equipment and individuals.

Options that involve a separate ground wire or bonding methods may allude to other safety practices, but the specific installation of type AC cable necessitates the inclusion of an insulated equipment grounding conductor to meet established safety standards. Only having non-insulated conductors would not provide adequate protection or compliance with these codes. Thus, the inclusion of an insulated equipment grounding conductor is both a matter of safety and regulatory adherence for wiring methods in assembly areas.
