The statement that best compares the influence of democratic and authoritarian systems of government on civil society is:
Democracies enable a strong civil society in which the people are able to influence their government, while authoritarian governments constrain civil society.
This is accurate as democracies typically promote freedoms, civic engagement, and pluralism, allowing citizens to actively participate in the political process, while authoritarian regimes often suppress civil society, limiting the ability of individuals to express dissent or organize politically.
