The mode is the score that occurs most frequently.

The time in months was 19 24 12 8 20 23 22 16 15 24 27 25 24 18 3 21 10 9 26 25[Original data set].

Ordering the number of months from least to greatest, we get:

3 8 9 10 12 15 16 18 19 20 21 22 23 24 24 24 25 25 26 27 [Arrange in order].

24 occured three times and no other score occured more than two times.

The time which occurs most often (the mode for the given data) is 24.

Answer: d. 24.
