This is a very simple question on finding out the range. You can hardly expect an easier question than this on Statistics.

Range = Maximum Value – Minimum Value

Of the given values, the maximum is 17 and the minimum value is 4. Therefore, Range = 13.
The correct answer option is D.

Hope this helps!
