The area between the graph and the x-axis on the given interval is approximately the sum of the areas of the rectangles with base length 1 and heights given in the table. Adding the heights of the rectangles from x=11 to x=19, we get: 1+2+3+4+5+6+1+0+0=22. Therefore, the best choice is C, which is the closest estimate to the calculated area.
