One way individuals can increase their individual influence on public policy is to volunteer to work at the polls and record votes for an election attend meetings of local government councils and committees become an active member of a political party or interest group follow the laws and report those who violate them to authorities

The third alternative is correct.

In a sense, all citizens participate in politics by exercising the right to vote. However, some people who are interested in participating more on the political scene can do so through membership of a political party or by joining a cause of interest. This may even be a first step towards a possible political career, although most people remain just behind the scenes.
