A) public debate.
B) monarchical rule.
C) education.
D) slavery.
E) security of property.

Both republican and liberal systems of thought believed that the foundation of freedom was the security of property. This idea is evident in the works of John Locke, a liberal thinker, and also in the writings of classical republicans such as Machiavelli and Montesquieu. The security of property was seen as a necessary condition for individual freedom, as it provided people with the means to pursue their own interests without fear of arbitrary interference or oppression from others.
