Final Answer :
C
Explanation :
The null hypothesis for testing correlation coefficient is that there is no significant relationship between the two variables being tested (i.e. correlation coefficient = 0). Option C is the only one with this hypothesis stated. The other options suggest that there is a positive correlation, which would be an alternative hypothesis, not the null hypothesis.
