Final Answer : A, Explanation :  The correlation coefficient of -0.75 suggests a strong negative linear relationship between variables A and B. This means that when the value of A increases, the value of B will generally decrease. Although the correlation coefficient does not indicate the strength of the relationship in terms of prediction accuracy, a correlation coefficient of -0.75 suggests that we can use measurements of variable A to make moderately accurate predictions of variable B. Therefore, option A is the correct answer.
