If it is found that r = 0, does that in that there is no association betwen these two variables? Choose the correct answer below. O A. No, because while there is no linear correlation, there may be a relationship that is not linear. O B. No, because if r = 0, the variables are in a perfect linear relationship. O C. No, because r does not measure the strength of the relationship, only its direction. O D. Yes, because if r = 0, the variables are completely unrelated.
