Final answer:
The appropriate verb to fill in the blank in the sentence is 'vivo' (Option C).
Step-by-step explanation:
The appropriate verb to fill in the blank in the sentence 'Hace cinco años que. en los Estados Unidos.' would be 'vivo' (Option C). In Spanish, the phrase 'Hace + period of time + que' is used to express how long something has been happening. The verb conjugation that follows should be in the present tense, as it refers to a current ongoing action or state. Therefore, the correct verb choice would be 'vivo', which means 'I live'. For example, the complete sentence would be: 'Hace cinco años que vivo en los Estados Unidos.' which translates to 'I have been living in the United States for five years.'
