In marx's communism manifesto, which of these policies is reflective of a communist state? free election, private property ownership, centralization of banks ( industry and public services, or unlimited individual choice.

Private property and centralisation of banks however in modern communist nations today they do like to censor media so it would hinder the unlimited individual choice because the only ideology they know is communism. elections are usually rigged also to keep a communist regime.

Cuz you will see it in real life situations
