While "faction" and "hegemony" may seem plausible, "coalition" accurately describes a governing alliance, making it the correct choice. "Incumbency" refers to the holding of an office or position, but here the reference is to the political group, not the officeholder's status. Thus, "coalition" is the best choice, as it accurately refers to a group that governs together.
