Final Answer : C, Explanation :  To find the variance, we need to first calculate the mean of the data set:(6 + 7 + 10 + 13) / 4 = 9Next, we need to find the difference between each data point and the mean, and square each difference:(6 - 9)^2 = 9(7 - 9)^2 = 4(10 - 9)^2 = 1(13 - 9)^2 = 16Then, we add up all of these squared differences:9 + 4 + 1 + 16 = 30Finally, we divide this sum by the sample size (n - 1) to get the variance:30 / 3 = 10Therefore, the variance is 10, and the best choice is C.
