Using a graphing utility or statistical software to plot the given data points and calculate the line of best fit, we can determine the equation of the line that best represents the relationship between body weight and drug dosage. The equation of the line of best fit can be used to predict the most effective dosage for a person weighing 120 lbs. Based on the data provided and typical methods for calculating a line of best fit (such as least squares regression), the prediction for a 120 lbs person falls closest to the option D, 13.88 mg. This is a simplified explanation; the exact calculation would depend on the specific method and tool used for finding the line of best fit.
