Libertarianism is a political ideology that

A) argues that governments are inherently repressive and should be abolished entirely.
B) argues that a single ruler should have total control over every aspect of people's lives.
C) argues for the need to place strict limitations on voting rights and civil liberties.
D) emphasizes freedom and voluntary association with small government.

Libertarianism emphasizes individual freedom and voluntary association with small government. While it advocates for limited government intervention in most areas, it does not call for the complete abolition of government like choice A suggests. It also does not support a single ruler having complete control like in choice B, and it does not advocate for restricting voting rights and civil liberties as in choice C.
