Answer:
"All ingredients in this product have been scientifically tested and clinically proven"
Explanation:
We can see that the Statement in the first option is right, that is, the ''...radio program host said, All ingredients in this product have been scientifically tested and clinically proven".
According to the question, the red flag the radio program host raised was about a nutrition-related product, and the claim is generally an indication that the information about the product is unreliable. So, in order words the radio program host was just encouraging people to use the product and calming peoples' fears down concerning the unreliability of the product because the product is tested and should be trusted.
Your audience should probably be adults. If adults learn the healthy habits of eating they can pass it on to their children and friends. Maybe posters or news segments could work to spread the news. This idea could work because adults watching the news segment and Billboards will choose not to pick up that snickers in the grocery store check out but instead trail mix.
Thats all you will need, just elaborate a bit more!
