Which line most accurately represents the line of best fit for the scatter plot?

A graph shows numbers from 0 to 21 on the x axis at increments of 3 and the numbers 0 to 63 on the y axis at increments of 9. Scatter plot shows ordered pairs 0, 27 and 3, 36 and 5, 37 and 7, 45 and 9, 45 and 9, 54 and 12, 54 and 15, 59 and 18, 63. A line labeled A joins ordered pair 0, 27 and 16, 63. A line labeled B joins ordered pair 0, 27 and 21, 45. A line labeled C joins ordered pair 0, 27 and 21, 31.5. A line labeled D joins ordered pair 0, 27 and 21, 18.
