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 because democracies typically promote freedoms of speech, assembly, and association, allowing a vibrant civil society to thrive. In contrast, authoritarian regimes often suppress civil society and limit the ability of individuals to influence government decisions.
