Final Answer :
D
Explanation :
A test-retest correlation measures the consistency of results over time, and it is generally accepted that a correlation of .70 or greater indicates good reliability. A correlation of -.40 would indicate poor reliability, a correlation of .00 would indicate no relationship between the two administrations of the questionnaire, and a correlation of .25 would indicate fair reliability, but not as strong as the recommended .70 or higher. Therefore, option D is the best choice as it meets the criteria for good reliability.
