Which statement would best serve as a claim for an argument?
food labels provide valuable information, including ingredients, nutritional information, and calorie counts.
though the information is sometimes challenging to decode, consumers should take the time to understand food labels.
allergy information is now available on all food labels, and warnings alert consumers about nuts, dairy, and gluten.
consumers rarely understand food labels because there are too many measurements cited.

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.
