In addressing emerging AI issues, frameworks that are specific to product safety, copyright, or criminal behavior may provide some indirect governance, but their applicability is limited compared to more direct regulatory mechanisms. Among the options listed, the Motor Vehicle Safety Act is the least effective in addressing AI issues as this act is specifically targeted towards the safety regulations of motor vehicles and is less applicable to broader AI issues that may involve data privacy, ethical considerations, and other non-vehicle-specific technologies. Therefore, while AI can be involved in vehicle safety, this act is less equipped to broadly address emerging AI issues beyond automotive safety standards. Hence, the correct answer is B, "The Motor Vehicle Safety Act."
