c) moderate negative linear correlation
d) little or no linear correlation

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
