Explanation:

You want the line that best fits the plotted data.

Best-fit line

A line of best fit can be determined to be "best" using any of several measures. Often, we want to minimize the squared error, the sum of squares of the vertical distance between a data point and the line.

Minimizing the error in this way tends to center the line between the points that would be the farthest from it. Here, line C is the one that runs through the vertical middle of the data set.

Line C is the best fit line, choice C.
