Thank you!

You are welcome.

Yes, "metropolitan" in the given context most nearly means "serving a major city" (option C). The word "metropolitan" refers to a city or urban area together with its surrounding suburbs and neighboring cities. In the context of the sentence, it indicates that the airport is located at the edge of a major city and is likely to serve the air transportation needs of that city and its metropolitan area. To arrive at this answer, you can look at the sentence and consider the meaning of the word "metropolitan" in relation to airports and cities.
