Which excerpt from the text most clearly establishes the connection between the pet food regulation industry and the accura cy of information on pet food nutrition labels?

"These officials run tests on food to make sure it meets its Guaranteed Analysis, the label on food that lists its ingredients and the proportion of each. However, the quality of regulation and enforcement varies from state to state, according to Born Free."

Explanation:

In the passage, "The Pet Food Industry", we are told that the history of pet foods can be traced to James Spratt, an American living in England who made the first pet biscuit.

Under the subheading, "Pet Food Regulations", we also learn that the Food and Drugs Administration does not have much control over the pet food as much as the State Control Officials. These officials ensure that accurate details about the food is published on the ingredient's list. They also ensure that the food produced is healthy for consumption through testing. This detail shows that the pet food regulation industry plays a vital role in the accuracy of information found in food labels.
