The sentence that has proper subject-verb agreement is:

Arizona and Nevada are states along the Colorado River.

The sentence that has proper subject-verb agreement is: "Arizona and Nevada are states along the Colorado River."

To determine if a sentence has proper subject-verb agreement, you need to make sure that the subject and the verb agree in number (singular or plural). In this case, the subject "Arizona and Nevada" is plural, and the verb "are" is also plural. Therefore, the subject and verb are in agreement.
