The answer is D. It is a positive correlation so I can't be negative. It also is a strong correlation so it cannot be 0.21. So the answer is D.

Answer:

D

Explanation:

The chart shows a strong positive correlation, hence this eliminates the negatives. Then 0.91 is a higher(strong) correlation coefficent.
