The slope of the saving schedule is calculated by dividing the change in savings by the change in income. From the given data, we can see that the change in savings is 40 (i.e., from 80 to 120) and the change in income is 200 (i.e., from 600 to 800). Therefore, the slope of the saving schedule is:

Slope = (Change in savings/Change in income) = 40/200 = 0.2 or 20%.

Hence, the correct answer is choice C) 20.
