If correlation coefficient is  -1 to -0.7  then it has strong negatively linear correlation.If correlation coefficient is -0.7 to -0.5 then it has moderate negative linear correlation.If correlation coefficient is -0.5 to -0.3 then it has low negative linear correlation.If correlation coefficient is -0.3 to 0 then it has no linear correlation.From above explanation if correlation coefficient is -0.55 then it has moderate negative linear correlation.Thus, option (c) is correct
