The correct answer is self-announcement and petition.
Self-announcement and petition are methods for a candidate to be placed on their party's primary ballot.
Self-announcement: the individual fills out papers and pays a fee to publicly announce that he seeks to be a candidate. Petition: Independent candidates must petition if they want to appear on the general election ballot.
A primary election is a process by which voters, show their preference for a specific candidate in a general election. The voters could be general public in an open primary, or members of a political party in a closed primary.
