A sample regression line is used to estimate the population regression line. It is not meant to show the actual relation between the dependent and independent variables, as that would be represented by the population regression line. The sample regression line connects the data points in a sample, but it does not necessarily maximize the sum of squared differences between the data points and the sample regression line. Therefore, B is the best choice.
