The correct answer choice to the question: What is a difference between a PAC and a super PAC, would be: PACs can contribute directly to candidates, but super PACs cannot.

Explanation:

PACs are generally known as political action committees and their direct purpose is to become an organization that receives donations and funds from members and supporters and directly play a role in a candidate´s campaign, a ballot, or a lawmaking process. However, PACs were placed under limitations as to how much money they could receive, and the sources of it, specifically corporations and labor unions, because they have direct impact on campaigns. In order to resolve that issue, super PACs, better known as independent-expenditure only committees, can receive unlimited funds from corporations and labor unions, as well as members, but these cannot go to impact a campaign. They can work with those funds in other ways, but not to impact a campaign, a ballot, or a lawmaking process.
