Question

political parties hold a national convention to do which of the following?
form a coalition government
present their campaign strategy to the media
nominate their candidate
organize the precincts for the coming election

Explanation:

In the context of political science (subfield: Politics), political parties' national conventions primarily serve to nominate their presidential (or other major office) candidate. Forming a coalition government is not the main purpose of a national convention (coalitions are more about post - election or inter - party alliances). Presenting campaign strategy to the media is not the core function of a national convention, and organizing precincts is done at a local level, not via national conventions.

Answer:

C. nominate their candidate
