Final answer:
The Safe and Accurate Food Labeling Act of 2015 is a federal law that created a voluntary labeling system for GMO products, aimed at creating a unified standard and potentially using a QR code for GMO information, rather than a mandatory text label that says 'GMO'. The correct option is b.
Step-by-step explanation:
The Safe and Accurate Food Labeling Act of 2015 is a federal law that was proposed to address the labeling of genetically modified organisms (GMOs) in food products. However, none of the options provided in the student's question accurately describe the Act.
The actual Act was designed to create a voluntary labeling system at the federal level, preventing individual state laws from implementing mandatory GMO labeling, thereby creating a unified standard across the country.
It posited some form of electronic or digital link, such as a quick response (QR) code, which could provide additional GMO information, rather than directly writing 'GMO' on food labels.
Regarding genetically modified foods, there has been an ongoing debate about their safety and the necessity of labeling, with the consensus among scientists being that GMO foods are no more harmful than traditionally bred crops.
Nonetheless, consumer advocacy groups and some members of the public continue to call for transparent labeling of GMOs in food products. The correct option is b.
