Testing whether the slope of the population regression line could be 0 is equivalent to testing whether the population coefficient of correlation could be 0 because the slope of the regression line is directly related to the correlation between the variables. If there is no correlation between the variables, then the slope of the regression line would be 0. The other options are not directly related to testing the slope of the population regression line.
