Question

according to nationalists, a nation - state’s government should be
led by an appointed president.
voted on by european parliaments.
chosen by that nation - state.
controlled by european monarchs.

Explanation:

Nationalism emphasizes the self - determination of a nation - state. So the government of a nation - state should be chosen by that nation - state itself. The option “led by an appointed president” doesn't align with nationalist ideas of self - determination. “Voted on by European parliaments” and “controlled by European monarchs” go against the idea of a nation - state's autonomy as they involve external control.

Answer:

C. chosen by that nation - state. (Note: Assuming the options are labeled as A. led by an appointed president, B. voted on by European parliaments, C. chosen by that nation - state, D. controlled by European monarchs. If the original labeling is different, adjust the identifier accordingly, but the correct option text is "chosen by that nation - state".)
