In the following question find out the alternative which will replace the question mark?

White : Black :: Up :? 

Down 

The answer is Down.

The analogy is between white and black, and up and down. White is the opposite of black, and up is the opposite of down. So, the missing word must be the opposite of up. Of the answer choices, only down fits this description.

The other answer choices do not fit the analogy. Argue is to disagree with someone, frown is to make a facial expression that shows disapproval, and south is a direction. None of these are opposites of up.
