Find the odd number / letters / word from the given alternative:

The odd one out is B. Good : Bad.

All the other options are opposites of each other.

• Valley : Depth – A valley is a low-lying area between hills or mountains, while depth is the distance from the top of something to the bottom.
• High : Low – High is the opposite of low, meaning above or at a great distance from the ground, while low is the opposite of high, meaning below or at a short distance from the ground.
• Black : White – Black is the opposite of white, meaning the darkest color of all, while white is the opposite of black, meaning the lightest color of all.

However, good and bad are not opposites. Good is a positive quality, while bad is a negative quality. They are not mutually exclusive, meaning that something can be both good and bad at the same time. For example, a person might be a good friend but a bad driver.
