Consumers would most likely use lobbying to accomplish the passage of new laws punishing offensive behaviors by companies. Lobbying typically involves organizing efforts to influence legislation and policy decisions, which aligns with the goal of advocating for new laws that hold corporations accountable for their actions.
The other options, such as gaining attention through negative news stories, resolving individual complaints, or pressuring a company through profit reductions, do not primarily fall under traditional lobbying efforts focused on legal and regulatory changes.
