Final Answer :
D
Explanation :
A positive correlation is needed to reflect that more office hour visits are associated with higher course performance. The correlation coefficient should also be of moderate strength to indicate a significant relationship, but not perfect (r = -1.00). Therefore, option D (r = .45) is the best choice, as it reflects a moderate positive correlation between asking for help in office hours and the improvement in course performance.
