To find the answer, we need to calculate the deviation of each score from the mean. 
Mean = (7+8+10+10+11+12+13+13+15)/9 = 11
Deviations:
7-11 = -4
8-11 = -3
10-11 = -1
10-11 = -1
11-11 = 0
12-11 = 1
13-11 = 2
13-11 = 2
15-11 = 4

Therefore, the deviation scores are: -4, -3, -1, -1, 0, 1, 2, 2, 4. The only option that matches this is B.
