Answer:
Specific, Phrased as a statement
Explanation:
They have to be specific so they can be used in an argument, and it must be phrased as a statement because you're making your position clear not asking a question. Do not select controversial because claims don't need to be in contrast with the other side, you can have a claim that is agreement with both sides, you shouldn't be controversial otherwise your claim wouldn't be neutral anymore it would be with any of the sides.
