The choice that is capitalized incorrectly in the given sentence above is "iraqi-american". This word should be "Iraqi-American". This choice should take the first letter capitalized because this is a specific name describing the word "tensions". It refers to the specific names of nationalities which are Iraqi and American.
As a grammar rule, every time the name of a country, nationality, or language is written, their first letter must be capitalized as they're proper nouns.
Both "Iraqi" and "American" refer to nationalities. Therefore, the correct writing would be "Iraqi-American".
