Final Answer : D, Explanation :  A correlation coefficient of 0.07 may be small, but it can still be statistically significant in large populations. It means there is a positive correlation between the two variables, but the strength of the correlation is weak. However, since statistical significance depends on various factors such as sample size and variability, it cannot be determined solely based on the correlation coefficient.
