This is because a correlation coefficient of -0.87 indicates a strong negative correlation between the two variables, meaning that as one variable increases, the other tends to decrease. A correlation coefficient of +0.86 also indicates a strong correlation, but in this case it is a positive correlation, meaning that as one variable increases, the other tends to increase as well. A correlation coefficient of 0 indicates no correlation, and a correlation coefficient of +0.3 indicates a weak positive correlation. Thus, A is the best choice as it indicates the strongest correlation.
