The correct answer is C) Promised their votes.
Political machines were organizations that focused on achieving a specific political goal. For example, a political machine may work to get one of their allies elected into an important position (like being mayor of a major city). In order to do this, political machines bribed individuals and companies for votes. For example, a political boss may give a big government contract to a company that would be willing to have their employees vote for the political boss or their ally in the next election. This corrupt cycle affected several major cities, including New York.
