B Correct answer
Explanation

The difference between the dry-bulb temperature (20 degrees C) and the wet-bulb temperature (8 degrees C) is 12 degrees C. Looking at the Dewpoint Temperature chart in the Earth Science Reference Tables, a dry-bulb temperature of 20 degrees C and a difference of 12 degrees C corresponds to a dewpoint of -10 degrees C.
