D On average, city B has the longer commute to work.
why
This is because the mean commute in city B is 22 miles, which is greater than the mean commute in city A, which is 17 miles. The range of both cities is not a good indicator of which city has a longer commute on average, as it only reflects the spread of values and not the central tendency. Therefore, option D is the best statement to compare the two commutes.
