Answer:
Federal Trade Commission (FTC)
Explanation:
Even though advertising agencies have their own self regulatory council (ASRC) that has been quite effective in establishing industry norms, the Federal Trade Commission (FTC) is the government agency that protects consumers from deceptive and unsubstantiated advertising.
The FTC prohibits misrepresentation, unfairness and any type of deception that may be portrayed in national advertising (inside the US).
