Answer:
The answer should be D, a ban of deceptive advertisements.
Step-by-step explanation:
In the 90s the government cracked down on deceptive advertising more than ever and more laws on the matter were added. The only other option that was actually ever banned was A, none of the other choices were ever banned. The ban on tobacco happened in the 70s under Nixon, that makes D the only possible answer. Hope this helps! :)
