Scenario 6-1 a Group That Calls Itself Adbusters Has a Site on Site

Scenario 6-1
A group that calls itself Adbusters has a site on the World Wide Web. The site contains many pages that address issues of consumption and culture, media practices and corporate responsibilities. For example, "the momentum has clearly accelerated. By some measures humans have used more physical resources since World War II than in all of history before it. It's now taking a toll beyond anything we could ever have imagined. What does it mean when one-sixth of the world's population consumes without any real restraint?"
Throughout the website, there are many references to advertising's role in creating and maintaining this situation. Not surprisingly, virtually all of the references to the practice of advertising are negative. (http://www.adbusters.org/home/)
-(Scenario 6-1) In the past, Adbusters cited 12 magazines that it said are responsible for pushing "a clean, exciting image for one of the dirtiest products around: tobacco." They suggested that Americans cancel their subscriptions to these magazines until the magazines stopped accepting this advertising. This is an example of

A) a yet-to-be-proved-effective tool called a boycott.
B) the activities of one of the three most powerful consumer organizations in the United States.
C) a group of consumers functioning as a regulatory agent.
D) a recently emerging phenomenon called consumerism.
