To find the rank of a score in a distribution, we need to first sort the scores in ascending order. The sorted distribution is:

1, 2, 4, 5, 6, 7, 7, 9, 10

The rank of a score is the position of the score in the sorted distribution. Since there are two scores of 7 in the distribution, we take the average of their positions to get the rank of 7. The positions of the two 7’s are 6 and 7, so the rank of 7 is (6 + 7) / 2 = 6.5.

Therefore, the answer is not one of the options provided.
