    Assuming C is -0.08, the answer is A. Brushing teeth more causes less cavities, so it's a negative correlation. -0.08 is a low correlation coefficient, so it's assuming mostly no relationship, when there is clearly a strong relationship, so the strongest negative correlation in the answers is A. -0.62.
