D) There is a weak relationship

The Pearson product moment correlation coefficient is used to measure the linear relationship between two variables. If the relationship between the variables is non-linear (curvilinear), the correlation coefficient will be close to zero even if there is a strong relationship between the variables. Therefore, we cannot conclude anything about the relationship between the variables based on this information.
