I could be wrong, but I would think 'verb'.
Hopes this helps!
Think about what a claim is. a claim is something that you state, even if you don't have proof. choice C is a fact, not a claim--it would be used as evidence to support a claim, but it doesn't serve as a claim itself.
i would say that B is the most appropriate claim to argue that people should be more nutritionally knowledgeable. choice D is almost a counterargument, in a sense, because it lists a flaw with food labels. choice A is a statement, but it can be proven with evidence--one could look at a food label to search for the listed items.
My initial thought was free verse. And you can make a point for it, but really think about it. How is it stating things. Do you feel like your there? Can you picture it? Yes, is the answer for this poem. I would go with D. Descriptive.
