The food and drug in ministration sets standards for a) advertising b) product labeling c) the environment d) traffic safety

option B) product labeling.

Justifictation:

On the site of the FDA you can read that this agency is responsible for assuring that foods sold in the USA are "safe, wholesome and properly labeled".

Aslo, in the same site, is written "the Fair Packaging and Labeling Act are the Federal laws governing food products under FDA's jurisdiction".

Furthermore, in the same site is the guide for labeling which you can download and see the requirements for labeling.

So, that information from the proper agency is the basis for the answer.
