When testing the significance of a correlation coefficient, the null hypothesis is that there is no correlation (the population correlation is 0). Therefore, the best choice for the hypothesis would be B, where r = 0. A correlation coefficient can only range from -1 to +1, so choices A, C, and D are not viable options.
