C Correct answer
Explanation

This question asks which event is NOT an ATP 500 tournament. Brisbane has always been an ATP 250 level event since its introduction in 2009, while Memphis, Hamburg (until downgrade), and Basel have all been ATP 500 events at various points. Therefore Brisbane is the correct answer as the 'odd one out' that has never been an ATP 500.
