The correct answer is B. 11

To find the range of a set of data, we need to calculate the difference between the maximum and minimum values in the set.

Given the data set: k+2, k-3, k+4, k-2, k, k-5, k+3, k-1, k+6,

The minimum value is k-5, and the maximum value is k+6.

Range = Maximum - Minimum

Range = (k+6) - (k-5)

Range =k + 6 - k + 5

Range = 11.

So, the range of the given data set is 11.
