A public disclosure law is typically aimed at requiring businesses and organizations to provide information that is useful for consumers and the public, often related to safety, efficiency, or health. The examples you've provided involve disclosures that inform consumers about the performance and characteristics of products.
Among the options listed, "efficiency reports of assembly line workers" would not be a result of a public disclosure law. This type of report is related to employee performance and is generally not disclosed to the public in the same way as product labels that inform consumers about fuel efficiency, nutrition, or energy efficiency.
