Answer: Choice B
Explanation: The colon (:) in the sentence "Here’s the thing about airplane food: it’s not exactly 'fine dining.'" is being used to **link two clauses**, showing a connection between the first and the second. So, the correct answer would be **Choice B**. The first part of the sentence introduces a topic (airplane food), and the part after the colon provides a specific statement about that topic. It's not introducing a quotation, so Choice A would not be correct.
