Explanation:
Fascist states are characterized by a one-party system. In such regimes, only one political party is legally permitted to exist, and all opposition is suppressed. Fascist Italy under Mussolini and Nazi Germany under Hitler both had single-party systems that monopolized political power. A zero-party system would mean no parties at all, which is not accurate. Two-party and multi-party systems allow competition, which fascism does not tolerate.
