Answer :
Based on the sentence provided, the correct phrase that best completes it is:
**C. tienes que**
Explanation:
1. In the sentence, the phrase "Aquí en el museo tú" is followed by the options "haber que," "hay que," "tienes que," and "tenemos que."
2. The phrase "tienes que" is the most suitable option in this context because it translates to "you have to" in English, which fits well with the sentence structure and the action of teaching the visitors different works of art.
3. The phrase "haber que" is not the best choice as it translates to "to have to" in English but does not fit smoothly in the sentence.
4. The phrase "hay que" translates to "it is necessary to" in English, which could work in the sentence but does not directly address the action of the subject (you) teaching the visitors.
5. The phrase "tenemos que" translates to "we have to" in English, which does not align with the subject (you) mentioned in the sentence.
Therefore, the correct answer to complete the sentence is "tienes que," as it accurately conveys the idea that "you have to teach the visitors different works of art."
