In a Wilcoxon Signed Rank Sum Test, the Test Statistic $D \neq 0$

In a Wilcoxon signed rank sum test, the test statistic is calculated as T = 45. The alternative hypothesis is stated as: The location of population 1 is different from the location of population 2. If there are n = 15 observations for which $D \neq 0$ , and the 5% significance level is used, then: $\begin{array}{|l|l|}\hline\text { A. } &\text {he null hypothesis will be rejected. }\\\hline \text { B. } & \text {the null hypothesis will not be rejected. } \\\hline \text { C. } & \text { the test results are inconclusive. } \\\hline \text { D. } & \text { the normal approximation must be used. } \\\hline\end{array}$
