Answer:
b. The Better Business Bureau's Children's Advertising Review Unit guidelines.
Explanation:
The Better Business Bureau produces the Children's Advertising Review Unit guidelines, which, as the name implies, provides guidelines for advertising to children younger than 12.
The goal of these guidelines is to make sure that advertising aimed at children is accurate, appropriate, and truthful, because children are particularly easy to manipulate.
Failure to meet these guidelines can result in intervention from the Federal Trade Commission, which can result in legal penalties from fines to imprisonment.
