Answer:

C is the correct answer.

Step-by-step explanation:

given: 12, 39, 21, 18, 24, 17, 12, 25

arrange them in increasing order:

12, 12, 17, 18, 21, 24, 25, 39

solve:

outlier refers to the unit which is minimum or maximum unit in the data.

Here outlier: 39

mean with the outlier:

(sum of units)/(total number) = (168)/(8) = 21

mean without outlier:

(sum of units-39)/(total number) = (168-39)/(7) = 18.4
