Answer:
b. he acted in good faith.
Explanation:
To act in good faith is to have honest intention and not want to harm other parties.
Ted's actions in promoting the product were based on his understanding of the state law. The fact that the law was not clear could cause the attorney general to think he intentionally acted against the law.
So if he makes it clear he did not intentionally act against the state's directive, he can claim he acted in good faith.
