Answer: d. 10 -13 and 14 -17

Because:

1) the range of the values is 10 to 17 (inlcude 8 numbers), which divided by 2 is 4, and the range of the selected classes is 4, so you can have two class interval of the same size, which is what the option d represents..

2) all the values are included (some pair of intervals excluded some numbers)
