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

The answer is C. Shallow : Deep.

In all the other options, the first word is the opposite of the second word. For example, dim is the opposite of bright, and wrong is the opposite of right. However, shallow and deep are not opposites. They are both adjectives that describe the depth of something. Shallow can mean “not deep” or “not far below the surface”, while deep can mean “having a great distance from top to bottom”.

Here are some examples of how the words in the other options can be used:

• The light was dim, so I couldn’t see very well.
• The answer to the question was wrong.
• The water in the pool was shallow, so I could only swim a few laps.
• The hole in the ground was deep, so I had to be careful not to fall in.
