<em>The answer is A. You could add statement A to the claim 3 as a supporting sentence. </em>
The outline is a little bit unbalanced as regards the supporting ideas. I would eliminate sentence C from claim 3. It doesn't contribute to the claim's main idea and it's just a generalization but not an important piece of information.
Also, you could make a separate claim related to the government's role in a free enterprise system and use sentences C, D, and C (from the last part) to support it.
