The correct order of terms to match the definitions provided is:

formal region (an area on Earth’s surface defined by relatively unchanging cultural or physical traits, often associated with a formal boundary)
functional region (an area on Earth’s surface defined by one or more linkages and activities occurring in that area)
perceptual region (an area on Earth’s surface with boundaries that are based on an individual’s perception, thoughts, and/or knowledge of people and their cultural traits, physical geography, and/or the built environment)

So the correct response is:
