Answer:
Hi!
The answer to your question would be option C. So the right sentence would be: With her move to Arenal—a small village located in the foothills of Arenal Volcano in Costa Rica—Lucia finally said goodbye to New York City.
Step-by-step explanation:
The lines in this sentence are called dashes. These dasheshave many purposes, among those is to show a pause or break in meaning in the middle of a sentence. In this particular case, for the writer to emphasize the information about Arenal, a pause is appropiate. This way he can separate this information from the rest of the sentence, which highlights the information about Arenal. Therefore, the answer is option C.
