The correct answer is D. I believe the federal government should not tax its citizens more than they can afford to pay.
Explanation:
The purpose of arguing in a text such as an essay or a speech is to prove through reasons and evidence specific point of view or perspective. Due to this, the main claim should express a point of view.
This does not occur in the first three options because these express facts or reality and due to this, it is not possible to try to prove these. However, the last option "I believe the federal government should not tax its citizens more than they can afford to pay" expresses a specific perspective that can be explained through evidence, and therefore it is appropriate to develop an argumentative text.
