In correlation, the absolute value of the r-value represents the strength of the correlation. Therefore, the strongest correlation is represented by an r-value with an absolute value closest to 1. Option C has an r-value of -.75, which has the highest absolute value among the given options and is therefore the strongest correlation. Option D is not a valid choice as r-values can only range from -1 to +1.
